his issue of Technology Today highlights the breadth of
Raytheon’s technologies, providing innovative solutions for
our international customers.
Raytheon Australia is the mission systems integrator of choice
for the Australian Defence Organisation and in 2012 became
Australia’s second largest defense contractor. Several of their
programs are highlighted in this issue, including the largest of their
current development projects, the Hobart Class Air Warfare
Destroyer, designed to protect the air and sea approaches to the
Australian continent.
Also featured is Raytheon’s collaboration with Australian universities
and government institutions — the University of Adelaide, the
University of Melbourne, the Bureau of Meteorology (BoM), the
Defence Science and Technology Organisation (DSTO) and the
Defence Systems Innovation Center (DSIC) — in conjunction with
the University of Massachusetts, to develop and distribute a network of phased-array radars to improve the prediction of
severe weather events.
In Glenrothes, Scotland, Raytheon UK is developing integrated circuit technology employing silicon carbide (SiC) capable of operating
at high ambient temperatures, for use in stressing system applications. The U.K. government, recognizing the potential of this
technology as an enabler for higher-efficiency systems, provides
partial support for this development under its Technology Strategy
Board “Materials for Energy” research program.
In Germany, Raytheon Anschütz has developed integrated navigation and bridge systems that provide small patrol craft with the
integrated navigation, command and control capabilities needed to
appropriately handle a broad range of tasks, from police duties to
military operations.
Also, located just outside of Hohenfels, Germany is the Joint
Multinational Readiness Center, where Raytheon, under the
Warfighter Field Operations Customer Support program (Warfighter
FOCUS), provides performance-based training in a genuine tactical
environment for U.S. and coalition forces. Discussed is Raytheon’s
role in developing training technology to ensure warfighter readiness.
Raytheon Canada Limited describes their next generation of High
Frequency Surface Wave Radar (HFSWR), which provides persistent,
active surveillance within a nation’s 200 nautical mile exclusive economic zone (EEZ). HFSWR is used by coastal nations to monitor

Feature
The worldwide growth of wind turbine farms has introduced new
challenges for air traffic management. The rotating turbine blades in
these wind farms generate radar returns that mask those of aircraft
being monitored by air traffic control radar. Over the past two
years, Raytheon Canada Limited, under contract to the U.K.
National Air Traffic Services, has developed a solution that has been
demonstrated at locations in the U.S., Holland and Scotland. This
system is described and test results are presented.
Raytheon enables safe air travel around the world as one of the
leading providers of Air Traffic Management systems. Raytheon’s
next generation ATM system, AutoTrac III (AT3), now operational
at three Indian airports, is highlighted. The AT3 system is an advanced, cost-effective solution to the challenges facing the ATM
community in the 21st Century — traffic growth outpacing revenue
growth and the drive to increase capacity and productivity in a cost
conscious environment.
Raytheon has a legacy of providing effective and reliable systems for
the defense of our homeland and that of our allies:
• Raytheon’s Multi-Spectral Targeting System (MTS) sensor —
which incorporates visible, infrared and laser-ranging intelligence,
surveillance and reconnaissance capabilities — is described. It is
currently deployed internationally by the U.K. Royal Air Force and
Italian Air Force on UAV platforms like Reaper and Predator, and
on numerous maritime helicopter platforms for Australia, Denmark, India, South Korea, Japan, the Philippines, Singapore and
Brazil, as well as several Middle East countries.
• For more than four decades, the Patriot system has provided an
international air and missile defense capability for the U.S. and its
allies and has been progressively upgraded to counter evolving
threats. A summary of Patriot’s history and recent modernization
are discussed.
• The European Phased Adaptive Approach (EPAA) is a ballistic
missile defense policy that begins with the protection of Europe.
The EPAA leverages Raytheon’s SM-3 family of missile interceptors,
as well as Raytheon’s AN/TPY2 radar. For SM-3, we are phasing
in progressive upgrades in warhead, propulsion and seeker performance to defeat the latest threats. We discuss SM-3 Block IIA

Integrated in Australia
Raytheon Australia’s expertise in
engineering and technology underlines
the importance of having a proven
capability and an experienced,
in-country workforce.
A
s a trusted partner of the
Australian Defence Force,
Raytheon Australia provides
mission assurance to its customers
through the delivery of world-class
mission systems integration and mission
support. Recognized as the second largest
defense contractor in Australia, Raytheon
Australia is underpinned by its unmatched
record of performance and in-country
capability to deliver solutions across
multiple domains.
Raytheon Australia’s approach to mission
systems integration includes:
• Undertaking capability trade-offs and
specifying mission and support systems
requirements.
• Architecting the system and defining the
integration strategy.
• Selecting technologies, subsystems, products and components in partnership with
the customer, and through the use of
trade studies and make/buy/reuse
processes.
Because of this, the company
has been able to draw upon highly
skilled local resources across Australia,
including the services of small to medium
enterprises and universities, in order to
effectively resource and execute programs.
Some of these programs are outlined
below.
Naval Systems Domain
Raytheon Australia’s largest design
and development project is the Air
Warfare Destroyer Combat System.
The Australian Hobart Class Air Warfare
Destroyer is designed to protect the air
and sea approaches to the Australian
continent, denying access to hostile ships
and aircraft, while also providing maximum freedom for action and response by
Australia’s own forces.
Hobart Class Air
Warfare Destroyer
Combat System
Raytheon
Australia also provides
in-service support for
the AN/BYG-1 (V) Combat
System on the Australian
Defence Force’s Collins class
submarine. Raytheon Australia has worked
closely with the Royal Australian Navy over
the last decade to transition the system
from the previous Rockwell/Boeing proprietary combat system to the current variant,
which is the same combat system that was
installed on U.S. Navy Virginia-class submarines. In its current role, Raytheon Australia
performs hardware and software development, as well as integration and test.
Raytheon’s Combat System upgrade exploits the power of sonar, electronic support
measures, radar, navigation, periscopes,
communication, command and control,
along with weapons to provide a fully
integrated combat system.

Naval
Communications
Station
Harold E Holt
Still in the naval systems domain and part of
Raytheon Australia’s base operations portfolio, the company provides maintenance and
support to the Naval Communications
Station Harold E Holt (HEH), meeting stringent operational availability requirements.
This is one of a small number of sites located
throughout the world that provide very low
frequency (VLF) communications to submarines. The low frequency transmission
antennas are more than 1,200 feet tall and
transmit a ground wave trapped within the
duct of the ocean and the ionosphere. The
low frequency transmission penetrates the
surface layer of the ocean, enabling submarines to communicate without surfacing,
thereby avoiding detection.
Aerospace Domain
Raytheon Australia pioneered the Retention
and Motivation Initiative (RMI), providing
the Royal Australian Navy with supported
aircraft to help the Australian Defence
Forces retain pilots and junior qualified
aircrew by enabling them to consolidate
and enhance their skills prior to flying
operational helicopters. Based on a
comprehensive analysis of customer needs,
Raytheon Australia acquired a fleet of Bell
429 world-class helicopters and developed
an efficient performance-based contract,
which provided an affordable turnkey
solution.

The Electronic Warfare Training
System (EWTS) represents a state-of-theart training system capable of jamming high
frequency through ultra high frequency
communications as well as radars. Raytheon
Australia specified, designed and developed
the system and is now supporting it with
comprehensive systems engineering, aeronautical and avionics expertise. After the
EWTS was integrated into the Lear Jet aircraft under Raytheon Australia’s direction, it
was then qualified and declared in service as
part of a 10-year maintenance and support
contract, which includes providing pilots
and training system operators.
Raytheon Australia’s integration of the
Radar Emulator Pod (EMPOD) provides
a missile radar simulation capability within
a composite pod structure. The emulator
pods are fitted to Royal Australian Air Force
(RAAF) fighter aircraft to support training.
Raytheon Australia performed the overall
integration of the EMPOD and its payload
and, following the successful development
phase, was awarded an ongoing contract
for support and maintenance. The EMPOD
and its payload were designed to replicate
the emissions from airborne and missile
threats during RAAF and Royal Australian
Navy exercises.
The Hornet Aircrew Training System
(HACTS) provides flight simulation of the
F-18 Hornet and, through a visual database, enables missions to be conducted
over local Australian terrains and airports.

subcontractor, the overall development and
integration of the hardware and software,
and conducted system integration at the
RAAF base in Williamstown.
Air Traffic Control Domain
Land Systems Domain
Joint Project 2072 Phase 1 is part of a
multi-phase project to digitize battlefield
communication for the Australian Army.
Phase 1 involves the delivery of Enhanced
Position Locating Reporting System
(EPLRS) radios, field support to the end
user, as well as training and in-country
maintenance. To date, more than 1,700
full-size and wearable radios, and more
than 7,000 subordinate items, have been
delivered.
The Australian Defence Air Traffic
System (ADATS) has primary and secondary surveillance radars that are distributed
across Australia. Raytheon Australia provides
maintenance and support for these radars
and the associated air traffic management
system, which includes a C-130 aircraft deployable system. ADATS uses equipment
from Raytheon UK in England, as well as
from Raytheon Network Centric Systems
in Canada and the U.S.

Raytheon Australia’s proven record of
performance is substantiated by feedback
from the Defence Materiel Organisation
(DMO) scorecard — a quarterly customer
report that tracks industry deliverables —
that has placed Raytheon Australia well
above its peers. The company’s high level of
performance is bolstered by its integrated
approach to technology and engineering, as
well as its trusted relationships with customers, suppliers and partners. •

aytheon Australia, the AWD Combat
System Mission Systems Integrator, is
executing an innovative program to design, integrate and test the AWD Combat
System, satisfying the Royal Australian Navy’s
demanding system requirements while working within crew, schedule and budget
constraints. The 6,500 metric ton Hobart
Class AWD is based on the Navantia Spanish
F100 ship design (above). It is being developed and built by the AWD Alliance, with
the Australian Government (represented by
the Defence Materiel Organisation) as
owner-participant, with ASC as the shipbuilder and with Raytheon Australia as the
Mission Systems Integrator. The first ship is
planned to enter service in the middle of
the decade.
The AWD program was defined in the
Australian Government’s year 2000 Defence
White Paper, which noted that the key to
defending Australia is controlling the air and
sea approaches to the Australian continent,
denying access to hostile ships and aircraft,
and providing maximum freedom of action for Australia’s own forces. This paper
announced the development of at least
three new Hobart Class AWD ships to help
reduce vulnerability of the fleet to air attack. Raytheon assisted in the analysis of the
AWD missions (Figure 1), thereby defining
key capabilities for the Hobart Class AWD
Combat System.
The AWD Combat System provides strength
in depth through interoperability with the
10 2012 ISSUE 2 RAYTHEON TECHNOLOGY TODAY
Australian Defence Force and regional and
deployed coalition forces, as well as interoperability with U.S. Navy assets as a tactical
area air warfare unit within a U.S. Navy carrier battle group.
The Australian government mandated that
the AWD’s principal air warfare capability requirements must be met by the Aegis
Weapon System in concert with Standard
Missile-2 (SM-2) and Evolved Seasparrow
Missiles (ESSM). Through selection of Aegis,
the Combat System exploits the proven
capability of the Aegis air and missile defense system, which has been deployed on
more than 90 ships worldwide. Maintaining
a baseline Aegis solution that is common
with the U.S. Navy is pivotal to leveraging the opportunities presented by Aegis
for performance upgrades and minimizing
through-life costs.
Raytheon Australia, as the AWD Mission
Systems Integrator, developed the overall
combat system architecture and provides
systems engineering resources to meet the
demanding Hobart class system specification
(HCSS) requirements.
System Architecture and Integration
Raytheon’s combat system architecture
design approach introduced the Australian
Tactical Interface (ATI) to act as a gateway
between other combat system components
and Aegis. This architecture preserves the
integrity of the existing Aegis fire control
system while eliminating any changes to
existing equipment interfaces. The approach
dramatically reduces cost and integration risk and it allows Australia to exercise
self determination over the selection and
through-life support of non-Aegis equipment. Figure 2 shows the interconnection of
the 35 major items of equipment.
The architecture is currently operational and
supporting system integration. This includes
the integration of the Hobart Class AWD
Combat System equipment, integration of
the combat system with the ship, and verification that the installed system solution
meets the HCSS requirements.
To ensure success, the integration and test
program is built around a set of key principles, including early integration and test
activities using physical equipment and highfidelity simulators, globally distributed
integration, evaluation of all interfaces and
the behavior of key functional threads, and a
risk-based prioritization of all tasks. The Aegis
Weapon System, the Australian Tactical
Interface and its associated sensors and effectors, the Navigation Subsystem, and the
Communications and Information Subsystem
are currently in the integration phase.
Raytheon’s responsibilities on the program
extend beyond the AWD Combat System.
Raytheon is also responsible for the development and operation of two key land-based
components located in Sydney, Australia:
• The Combat System Through-Life
Support Facility initially enables AWD

integration and test, and then transitions
to an engineering support role.
• The Hobart Class Command Team
Trainer is a high-fidelity Combat
Information Center simulator used to
teach ships’ command teams how to
operate the ship’s systems in the most
effective way.
Challenges ahead include completing the
combat system integration onto a ship,
conducting sea trials, and verifying that
the installed combat system meets HCSS
requirements. The program is confident in
its success because the integration and test
strategy has been aligned from the outset
with the program’s architectural vision, principles and key features. The Hobart Class
Combat System promises to be the most
capable surface combatant ever to be put in
operation by the Royal Australian Navy. •

Weather Radar Research in Australia
Addressing the need for faster, more accurate weather warnings
C
urrent weather monitoring radar systems are large,
high-powered and expensive. They are designed to provide
long-range surveillance over large
areas. Terrain blockage and sighting limitations, including those due
to the Earth’s curvature, result in
less than complete spatial coverage (Figure 1). In addition, radar
images in conventional, mechanically rotating, systems are updated
only every six to 10 minutes. This
can be a problem because the life
cycle of a convective weather cell is
around 30 minutes and its severe
components, such as microbursts, can
develop and dissipate between scans.
This limits the accuracy and timeliness
of weather forecasts and warnings.
Raytheon and its partners are investigating alternative networks of smaller,
less expensive radars to fill these gaps.
Raytheon has been working with
the University of Massachusetts
Collaborative Adaptive Sensing
of the Atmosphere (CASA) center
for the past 10 years to eliminate
this gap. In addition, Raytheon
has recently started a research
relationship with the University of
Adelaide in South Australia to expand this research and to address
weather and hydrology needs
around the globe.

conventional weather radar coverage.)
*X-Band – Electromagnetic radiation in the frequency range of 8GHz to 12GHz.
**Polarimetric – Transmitting and receiving in both horizontal and vertical polarizations.
Feature
The ability to multitask such systems, and
to potentially integrate them with air traffic
control or other similar systems, is an area
of interest for research and development.
The benefits of multitasking could greatly
affect the architecture and efficiency of new
systems. These include the ability to maintain broad and persistent spatial coverage
to detect and track precipitation and other
atmospheric phenomena (e.g., smoke and
insects), while simultaneously providing narrow time resolution data on critical weather
events such as tornadoes and localized
areas of dangerous precipitation. This would
be interleaved with information about aircraft close to these events and potentially in
harm’s way.

Raytheon’s small phased array radars fill the gaps in radar coverage.
This new technology also provides
advanced digital signal processing
techniques to improve performance.
For example, the investigation of
weather effects is enhanced by the simultaneous allocation of phased array
beams to different volumetric regions,
as well as the adaptive allocation of
these beams to track and delineate
weather effects on spatial and temporal scales with resolutions greater than
those in current use. The benefits of
improved spatial resolution can be
seen in Figure 5, with the higher resolution display on the right allowing
improved geographical localization of
weather patterns as compared to the
lower resolution results on the left.
The proposed new approach significantly augments existing systems by
providing high temporal and spatial
resolution and faster scanning at key
locations such as airports and areas
where the views of large radars are
obstructed.
While weather monitoring services
remain a prime application for the
proposed system, another important
application is meteorological research.
Rapid updates provided by the phased
array antennas will give new insights
into cloud processes. Polarimetric
functionality provides more detailed
information on cloud microphysics, including the shape of particles,
which can differentiate rain from
hail. Observations supplied by the
proposed system will enable robust
testing and high spatial resolution
meteorological research models.
Such testing is critical for understanding and monitoring the effects of
climate change and the processes
that affect it.
A network of distributed phased
array radars provides not only greater
multitasking flexibility, but it also allows for greater spatial coverage.
While there have been some limited
demonstrations in the use of a single
phased array for weather monitoring, there has never been a practical
demonstration of the coordinated
use of networked phased arrays for
monitoring weather phenomena.
The system being developed places
the current Adelaide facility at the
forefront in the development of
practical weather radar system technology. This radar system will provide
strategic guidance to the Australian
Bureau of Meteorology for future networked radar systems with regard to
monitoring weather events, extreme
phenomena and multitasking. •

High-Temperature Integrated Circuits (ICs)
Providing performance in extreme environments
E
lectronics today are dominated by
semiconductor devices and ICs that
are fabricated on silicon. As a result,
most electronics are limited by the reliability
and efficiency of their silicon devices to
operate in environments where the temperatures of the silicon transistor junctions are
kept below 125ºC, with silicon insulator
forms offering solutions up to 225ºC.
However, there are system applications
where electronics must operate at higher
temperatures for improved system performance. For these applications, alternative
semiconductor materials must be used that
do not have silicon’s temperature limitation.
One of these materials is silicon carbide (SiC).
SiC power components are emerging as
viable alternatives to silicon power components; silicon carbide can also be used to
make integrated circuits, where logic gates
and analog components are combined to
perform sensing and control functions while
operating at high temperatures.
High-temperature SiC integrated circuit
technology (Figure 1) is under development
by Raytheon in Glenrothes, Scotland. The
U.K. government, recognizing the potential
of this technology as an enabler for higher
efficiency systems, provides partial support for development under its Technology
Strategy Board “Materials For Energy”
research program. This technology will
support the manufacture of complementary
metal-oxide semiconductor (CMOS)
integrated circuits that use SiC semiconductor material.

at temperatures up to 300ºC.
Table 1 compares selected properties of SiC
with silicon. The wide bandgap property of
SiC corresponds with low leakage current
for SiC transistors at high temperatures,
whereas the leakage current in silicon
transistors (having a narrower bandgap)
increases significantly with temperature,
ultimately causing device failure. It is predominantly this characteristic that enables
silicon carbide devices to operate reliably
and efficiently at temperatures well above
that of silicon devices.

Gas Turbine Engine Application
Raytheon is applying SiC technology to a
European Union-funded aerospace research
project under the Clean Sky program. One
of the program goals is to develop technologies that reduce aircraft noise and
increase fuel efficiency. If the fuel efficiency
of a jet engine is improved, and its weight is
reduced even by a small amount, total fuel
consumption can be significantly reduced
over the service life of the aircraft. One way
to improve engine efficiency is to better
control the combustion process. This requires accurate temperature sensing of the
hot gases as they flow through the engine.
Raytheon is working with Aero Engine
Controls (Rolls-Royce Goodrich Engine
Control Systems, Ltd) to evaluate materials used in the engine control system.
Raytheon’s high-temperature SiC CMOS
circuits are being evaluated as a way to
improve the accuracy of temperature
measurements taken at critical locations
on the gas turbine engines.
Figure 2. A “see through” image of a gas turbine engine shows the current locations for temperature measurement electronics (red circles). SiC technology enables the electronics to be
mounted closer to the hot engine exhaust. This improves exhaust temperature measurement
accuracy — and better accuracy results in improved engine efficiency.
The temperature of a gas turbine engine
increases from the intake to the exhaust
throughout the length of the engine

worked for a large semiconductor company in
equipment development and yield improvement, which provided her initial background
and experience in semiconductor processing.
Commenting on key experiences in her career,
Cormack notes that, “Throughout my time
in process engineering, I held a variety of
roles and took on operations management

and increased process yields. She then took
on a lead role for developing the SiC business

technology and the achievement of industry

Feature
in the combustion chamber and exhaust
sections. Due to the limitations of current
silicon semiconductor technology, sensitive
temperature measurement electronics must
be remotely located near the cooler intake.
Specialized cabling runs the length of the
engine to the sensing elements near the exhaust. This long cable is expensive and must
be routed through engine compartment
bulkheads, adding extra weight and cost.
Additionally, the long cabling introduces
electronic noise and adds signal loss to the
sensing system, which reduces the accuracy
of the temperature sensing function.
Raytheon and Aero Engine Controls are
working together to develop a thermocouple
signal multiplexing unit that uses high-temperature SiC CMOS technology. When fully
developed, the SiC CMOS circuit should operate reliably and efficiently at temperatures
up to 300ºC, allowing the unit to sit closer
to the sensors at the hot end of the engine.
This facilitates more accurate and failsafe
sensing. After multiplexing and amplification,
the sensor data can be sent via simple and
inexpensive twisted pair cabling back to the
main control electronics module mounted
within the cool section of the engine.
High Temperature Power
Converter Application
SiC is an emerging alternative to silicon
semiconductors for use in the power
switches and rectifiers employed in power
supplies. The SiC material properties of
higher breakdown electric field, higher
bandgap energy, higher thermal conductivity and a higher saturated drift velocity
are desirable because they allow switches
to operate at a higher efficiency with
higher switching speeds, higher voltages
and higher power densities. SiC, which
combines these properties with the ability
to operate and maintain its efficiency at a
higher temperature, represents an enabler
for many new power applications.
In power supplies, the higher (5 to 10 times)
switching speeds of SiC power switches
allow the associated energy storage components (inductors and transformers) to
be proportionally smaller — reducing their
weight and volume by the same factor.1
Power densities of 30 kW/l have been
reported.2 Additionally, higher allowable
device junction temperatures and high thermal conductivity reduce the need for bulky
thermal management solutions, leading to
smaller, lighter and more densely packaged
power converter modules. Dense packaging, in turn, enables the close integration of
control circuitry. This minimizes series inductance, improving stability and efficiency.
Raytheon’s high temperature SiC CMOS
technology will provide solutions to the
challenges of achieving higher performance
with greater energy efficiency in extreme
environments. This new development
provides opportunities with new classes
of products, all enabled by high operating
temperature electronics. •

T
oday’s modern navies face new challenges. While there continues to be
a need to maintain readiness for
traditional conflicts, navies must also be
prepared to counter smaller and more volatile threats, such as those posed by pirates,
warlords or terrorists, often operating from
remote locations.
To counter these asymmetrical threats, large
ships with complex combat management
systems (CMS) are often deployed. These
systems must be operated by a large number of well-trained and experienced
personnel located in the ship’s combat information center (CIC). This level of
response, however, can be an inefficient and
sometimes inappropriate use of resources.
Smaller vessels (e.g., patrol boats generally
less than 60 meters in length) may be more
suitable for countering these threats, but the
navigation and control equipment on such
vessels typically consists of various highly
specialized individual or loosely integrated
components from different suppliers. This
makes it difficult to achieve an acceptable
level of operational efficiency under the
control of a single operator, or even a
small crew.
To fill this gap, Raytheon Anschütz GmbH

integrated, scalable navigation system using
commercial off-the-shelf (COTS) equipment (Figure 1). The new bridge system
provides patrol boats — those without
the resources of a large ship — with the
integrated navigation and C2 capability
needed to appropriately handle a broad
range of threats. This includes the capability to acquire, integrate, analyze and act on
data from multiple sensor systems including
tactical radars, the maritime automatic identification system (AIS), electro-optical (EO)
sensors (high definition television [HDTV]
daylight camera, infrared [IR]-night sight
and laser range finder), sonar, electronic
support measures (ESM) sensors and classic
navigation sensors. The Synapsis architecture is the world’s first navigation system
that has been type approved according to
the International Maritime Organization’s
new performance standards for Integrated
Navigation Systems (INS).

police duties, in addition to the normal navigation and C2 functions, vessels are equipped, at
a minimum, with an EO/IR camera controlled by the Synapsis Bridge System. For police or

Interdiction and Military Tasks
For police interdiction and military tasks,
the baseline software package — radar,
Electronic Chart Display and Information
System (ECDIS), conning (display of navigation sensor data/alarms) and the integration
of navigation sensors and steering control — is extended to include additional
functions such as command and control,
electro-optic sensor control and processing,
and weapons control.
The Synapsis Command Bridge configuration can include integrated tactical track
management, a tactical database, a small
target tracker and an optical tracker with a
calculation of the fire control solution for
weapons engagement. All of these systems
can be operated by the Synapsis Command
Bridge. Additional stand-alone consoles for
the camera or the weapon systems are not
necessary because all relevant elements are
already included.
In most cases, all data from the optical
tracker is sent directly through the bridge
system. This leads to a short time delay
between picking up new track information
and sending it to the weapon. When there

directly to the weapon. This may be used,
for example, to engage very fast targets
such as aircraft.
A significant advantage of this system is
its flexibility. At any time, individual components can be added to or removed from
the integrated navigation system to create
customer-specific solutions. The starting
point is the integrated navigation bridge.
All other hardware and software components can then be integrated into this
baseline capability.

Raytheon Anschütz has recently tested
and delivered the Integrated Navigation
and Bridge System to outfit a new class
of reconfigurable offshore patrol vessels,
the RiverHawk Advanced Multi-mission
Platform (AMP-45), developed for U.S.
domestic and international customers.
The AMP-45 (Figure 3) was developed by
RiverHawk Fast Sea Frames of Tampa, Fla.,
in partnership with Raytheon Anschütz.
The AMP-45 features a compact, efficient
ship layout for operation by small crew
sizes (generally a two-person bridge crew),
and it is equipped with the systems needed
for exercising national and multi-national
maritime security responsibilities throughout the exclusive economic zone (EEZ). The
RiverHawk AMP series incorporates design
features focused on mission performance,
reconfigurability and low life-cycle cost.
The Synapsis Command Bridge features a
new generation of intelligent multifunctional workstations that combine nautical
functions such as radar, chart radar, ECDIS
and conning, and also permit the integration of additional applications and data.
Its scalability makes it perfectly suitable to
meet any ship type requirements — from
a basic system to more advanced systems
that comply with the new integrated navigation system performance standards. The
Command Bridge can be paired with additional shipboard functionality — such as
the ship’s network, communications and
control systems — to offer a total integrated shipboard electronics capability. It
may also be integrated with a full combat
management system on larger platforms to
provide seamless situational awareness between combat and bridge operations. •

Warfighter FOCUS
Feature
Raytheon engineers in Germany provide a
broad range of solutions to Warfighters
Through the Warfighter Field Operations Customer Support (FOCUS) program, Raytheon provides
training and training support services to U.S. government agencies and foreign governments.
Warfighter FOCUS provides fully integrated live, virtual and constructive (LVC)1 training operations and
support systems to locations worldwide. Warfighter FOCUS is the first program to provide integrated
support for LVC training environments.
Under the Warfighter FOCUS contract, Raytheon leads the Warrior Training Alliance (WTA), a team of member companies that provides
worldwide integrated training support services for operations, maintenance, sustainment and training for devices, simulators, simulations
and ranges. This total life-cycle contractor support of U.S. Army worldwide LVC training systems, which includes operations and maintenance (O&M) systems integration and engineering support services, is made possible by 7,000 WTA personnel who support soldiers at
more than 600 sites.
Feature
Warfighter FOCUS
The “graduate school” for collective Army
training is the Combat Training Center
(CTC) rotation. In peacetime, a Brigade
Combat Team (BCT) will go through a CTC
rotation approximately every 18 months.
During periods of active conflict, each BCT
that is to deploy into an active combat
theater is required to successfully complete a CTC rotation within 120 days of
deployment. At the CTCs, the Army seeks
to replicate the sights, sounds, smells and
stress of actual combat. The combination
of challenging terrain, full-speed operational tempo, ruthless opponents and an
objective cadre of referees is further augmented by an intrusive press corps and a
culturally accurate indigenous population.
The resulting environment is as realistic
and stressful as possible without the taking of life. This is the precise environment
that the Army has intentionally constructed
and that Raytheon’s Warfighter FOCUS
program supports. With all of these factors
present, the CTCs represent the pinnacle
of live training — where everything is real
except the bullets.
One of the Warfighter FOCUS-maintained
CTCs is the Joint Multinational Readiness
Center (JMRC) located just outside
Hohenfels, Germany (Figure 1). The JMRC
is one of three Army Maneuver Combat
Training Centers (MCTCs) where soldiers
experience near-battle realism and fully
integrated LVC training. The focus on
performance-based training in a genuine
tactical environment measured against
established tasks, conditions and standards
provides U.S. and NATO armed forces
with a realistic, instrumented training environment for conducting full-spectrum
operations. More than 60,000 soldiers
(U.S. and allied) train at the JMRC annually. No other means of training so closely
replicates battlefield conditions, simulates
weapons effects, records results of engagements, allows expert-assisted analysis

of unit actions and provides the Army with
the ability to efficiently distribute lessons
learned from the battlefield throughout
training.
Due to the extensive scope and reach of
modern combat, simple observation is
insufficient to capture all of the activities
that objectively describe the events of a
training scenario. An instrumentation system (IS) provides this capability through an
integrated system-of-systems comprised
of workstations, databases, voice and
video recording, production and presentation equipment, interface devices, and
communications systems that manage
the tracking and event data for all of the
instrumented participants and constructive
entities (e.g., vehicles).
Raytheon engineers working in Germany
on the Warfighter FOCUS program provide
full life-cycle support to the JMRC IS
through service life extension projects
incorporating capability enhancements
that support the latest military equipment,
tactics and training concepts. The following
are a few examples of how these engineers
have delivered innovative, flexible, costeffective, integrated solutions to meet the
needs of the warfighter.
Instrumentation System Video Control
and Edit Upgrades
There is an abundance of sensors and attendant data; but in order to provide effective
feedback, that data must be assimilated and
analyzed in a timely manner to support the
scenario’s fact-based after-action review
(AAR), which is held while the real events
are fresh in the participants’ minds. The information that AARs provide identifies how
to correct deficiencies, sustain strengths
and focus on the performance of specific
mission-essential training objectives. In an
AAR, soldiers view playbacks of actual footage taken and hear radio communications
recorded during their simulated combat,
which improves soldier and unit readiness
before they deploy to real-world conflict.
The standard for conducting a small unit’s
AAR is two hours, and for a brigade, six
hours, after the conclusion of the training
scenario.
The need to hold an AAR soon after the
completion of a training scenario requires
that the process of preparing an accompanying video proceed quickly. The video
segment of the original IS at the JMRC consisted of an outdated analog video system
that used VHS tape decks for recording and
subsequent playback at AARs. The system
was not portable and required analysts to
develop AAR video in a formal production
Feature
center environment. This labor-intensive
operation required a staff of skilled video
editors and producers working alongside a
training analyst and a feedback analyst.
This process was capable of producing
only a few videos for use in AARs on any
given day.
To reduce AAR production timelines, analyst
workload and specialized staffing requirements, Raytheon engineers developed and
fielded a fully integrated digital video system with record, edit, control and playback
capabilities. This system also routes video
for cutting and editing to a shared server
where it is accessible from any analyst’s
workstation. The system is modular for ease
of maintenance, portable for use at off-site
locations and flexible for use with multiple
computer operating systems.
Due to Raytheon’s improvements, training
analysis and feedback (TAF) analysts can
now capture video that correlates with any
moment in time and can select pertinent
video clips, which are later spliced together
automatically by the new system. TAF analysts can now produce most videos without
any assistance from specialized personnel.
The edited videos are available on all workstations for easy access. The audio selections
presented in the AAR can be chosen in a
similar fashion and linked to the video. The
finished product is easily accessed online
or copied to a DVD. The result is an easy to
use, intuitive system manned by fewer and
less specialized people. Videos are produced
in near real time, giving the soldiers more
timely feedback.
Range Data Measurement Subsystem
(RDMS) Rehosting and Precision RealTime Location System (PRTLS) Tracking
Another key component of the JMRC instrumentation system is the RDMS, which
provides the conduit for carrying time/
space/position information (TSPI) updates
and real-time casualty assessment (RTCA)

back to the computational and display
portions of the IS. Shown in Figure 2, the
RDMS includes software that enables up to
2,000 live training entities to be tracked and
managed. Raytheon engineers rewrote parts
of the original RDMS software to replace
proprietary, aging and costly-to-maintain
systems with a government-owned openarchitecture solution.
In addition to the renovated software, the
updated RDMS system leverages Raytheon’s
PRTLS radio and software components. The
RDMS extends them for use with vehicle
detection devices (VDDs) and man-worn
individual weapon system (IWS) vest systems
(Figure 3), and is designed to easily interface
with future devices.
The PRTL system is easy to set up and can
be readily adapted to work at other training
areas. The system uses open standards on a
commercial radio and it works well in cluttered environments such as wooded areas.
Feature
Warfighter FOCUS
The software is developed and furnished
with full government rights. The biggest
benefit of RDMS, however, is cost effectiveness. The life-cycle cost of this new system
is approximately one-twentieth of the cost
of the system it replaces.
Pairing the PRTLS with a data communications interface (DCI)-embedded computer
provides translations of routed data from
the detection device to the IS. The DCI is
small, lightweight and can be worn in the
IWS vest along with the soldier’s radio and
battery. All tracking is done from the global
positioning system in the radio. This allows
for tracking, even in situations where the
detection device has failed or no onboard
GPS system exists (Figure 4). With a simple
switch between mounting hardware and
cable, the same DCI and radio can be used
for vehicles or individual warfighter (manworn) devices. This versatility also reduces
life cycle costs and down time.
Exportable Instrumentation
System (EIS)
The EIS was born out of a need to take
the CTC experience to remote locations; in
effect, bringing the training center to the
soldier. Utilizing the EIS can shave weeks
of travel off of a soldier’s time away from
home base, while still providing the fullscale, high-quality combat training ordinarily
experienced at a stationary CTC.
This system includes the ability to equip
participants and provide a tracking and
engagement capability similar to that of the
JMRC instrumentation system’s fixed site.
The EIS fits digital video, digital audio,
observer controller communications and
AAR presentation facilities into portable,
airmobile containers, transportable anywhere in the world by air, truck, rail or
sea. The system is also DoD Information
Assurance Certification and Accreditation
Process (DIACAP) certified for compliance
with DoD security requirements.

rotecting a nation’s sovereignty and
effectively managing the natural resources around its coasts place new
demands on the organizations tasked with
surveillance and enforcement. As a general
principle, the level of surveillance required
at any given time depends on the perceived
threat. The ideal surveillance system must
be capable of normal, day-to-day operation
for the lowest possible cost, yet have the
integrity to allow enforcement agencies to
respond decisively and economically when
required.
Until recently, such a surveillance system did
not exist. Now, however, shore-based high
frequency surface wave radars (HFSWR) developed by Raytheon can provide persistent
(continuous), cost-effective, over-the-horizon surveillance up to and beyond the 200
nautical mile limit of the exclusive economic
zone (EEZ*). Surface wave radar developed
by Raytheon Canada Limited, a leader in
surveillance and navigation systems, is the
only land-based radar with this capability.
The need for persistent surveillance is illustrated by an incident that occurred on

Pavit, grounded on Juhu beach in Mumbai,
India (Figure 1). It was later determined
that the vessel was abandoned on June
29 near Oman. The vessel drifted into the
Arabian Sea and entered India’s EEZ. The
MV Pavit passed undetected through one
of the world’s busiest shipping lanes during a heightened level of alert following
the Mumbai terrorist attacks. In doing so,
it passed through three tiers of security —
the Navy, the Coast Guard and the Coastal
Wing of the Mumbai Police — before eventually grounding. Had an HFSWR been
installed, this vessel could have been observed as it entered the Indian EEZ and
appropriate action could have been taken.
Surface wave radars operate in the high frequency (HF) portion of the radio frequency
(RF) spectrum. As illustrated in Figure 2 (following page), the lower the frequency of
operation the greater the detection range.
Unlike traditional microwave radars whose
detection range is limited to the line-of-sight
horizon, HFSWR signals follow the curvature
of the Earth due to ionospheric refraction at
the frequencies in which they operate. This
enables the detection of surface vessels at
significantly greater ranges.
HFSWRs operate in a pulse-Doppler mode,
emitting a coherent pulse train where the
phase of the signal is precisely controlled
from pulse to pulse. The radar’s area of
coverage is symmetrical around the radar’s
boresight, where the boresight is perpendicular to the axis of the array. Returns

from beyond +/- 60 degrees in azimuth are
typically not displayed due to a rapid falloff
in system performance. The echoes from
objects within the area illuminated by the
radar are received by a linear array of antennas (Figure 3) and are digitally processed to
enhance detection of the wanted echoes.
The returning echoes are sorted according
to range, velocity (Doppler) and bearing.
The echoes are then compared against a
detection threshold chosen to achieve a
certain value of constant-false-alarm-rate
(CFAR). If the magnitude of an echo exceeds
the threshold, it is declared a detection. A
tracking algorithm associates successive
detections to form a track. The ability to
form tracks enables the radar sensitivity
to be increased by lowering the detection
threshold (thereby increasing the false alarm
rate), since only those detections that are
consistent with the established track are
displayed. In this way, HFSWR conveys to
the user only those tracks corresponding to
real vessels. The track history also allows
the operator to visualize the activity of the
vessel and highlight anomalous or suspicious behavior.
The maximum detection range of HFSWR
depends on many factors. These include
the transmit power, radar frequency, radar
cross section of the target, target range,
background noise, and interference level as
well as sea-state. Of these, only the transmit
power and transmit frequency are under
the control of the radar. Both the noise and
interference levels are dependent on the
geographic location of the radar site, timeof-day and season, and also on the level of
sunspot activity.

Generally, at the lower end of the HF-band
the noise level increases at dusk and remains high through the hours of darkness.
Also, during the hours of darkness there
are high levels of co-channel communication interference from distant HF users. As
a result, the radar operates with a reduced
range at night. Raytheon’s HFSWR system,
however, is equipped with a number of
patented signal processing functions that
mitigate the effects of some of these interferences. Typical performance is illustrated
in Figure 4.
Since HFSWRs are tracking radars, object
classification based on track history is possible. From this track data, anomalistic
vessel behavior can be observed and used
to heighten awareness of suspicious activity.
Examples of anomalistic behavior observed
by the radar are shown in Figure 5. In the
first example, the vessel track was dropped
and subsequently re-acquired. Analysis of
the distance and time between the termination of one track and the initiation
of the new track indicated that the vessel
rapidly slowed down and remained stationary for approximately 10 minutes before
re-embarking on its journey. The system
highlighted this to the operator as being an
anomaly. This behavior was indicative of a
vessel that had transferred cargo to or from
another local vessel. In the second example,
the radar tracks a vessel that left port heading east-north-east. At a range of 70 nm
from shore, the vessel, now well outside
the range of traditional coastal surveillance
radars, made an abrupt 90 degree course
change and began to head in a north-

westerly direction, which in this case was a
maneuver that raised security concerns. An
intercept of the vessel was undertaken.
The high frequency surface wave radar
was developed by Raytheon to meet the
need for persistent surveillance of the strategically significant EEZ. It was designed
to convey to the user high-quality tracks
corresponding to real vessels, allowing
anomalous or suspicious vessel behavior to
be readily identified and patrols dispatched
to investigate further. •

Dr. A.M. (Tony) Ponsford is a technical director for Maritime Domain Awareness (MDA) at
Raytheon Canada Limited (RCL), specializing
in high frequency surface wave radar (HFSWR)
and integrated maritime surveillance (IMS)
technologies. Ponsford addresses the importance of putting the customer first and
foremost: “In my dual role of representing
Engineering and Business Development, I get
to meet customers and their scientific staff.
Together, we develop a solution to the problem
that they are facing. The solution
often encompasses engineering and financial
challenges, as well as cultural. We then get to
transition the solution into a program that
meets the requirements and budget constraints
of the customer. It is rewarding when the relationships developed outlast the project.”
Ponsford’s MDA career started with his serving
in the Merchant Marine, where he worked with
Shell Tankers in developing concepts for MDA.
In the 1980s, working as a research associate at
the University of Birmingham, he initiated the
development of the HFSWR for persistent surveillance of a nation’s 200 nautical mile
exclusive economic zone (EEZ). In 1987, as
senior scientist, manager and technical director
for NORDCO’s newly formed IMS business
unit, Ponsford established Canada’s first
HFSWR test bed facility at Cape Bonavista in
St. John’s, Newfoundland. This effort eventually
progressed into the world’s first shore-based,
real-time, EEZ surveillance sensor used to provide the continuous, all-weather tracking of
ships, icebergs and aircraft within the EEZ.
Ponsford collaborated with NASA, the
Canadian Space Agency and Western
University to develop a high frequency line-ofsight radar to detect and track meteors. He also
designed HF radar systems for the U.S. government to track cruise missiles and theatre
ballistic missiles.
“Engineering is a tough but rewarding profession,” Ponsford relates. “Every day brings new
challenges. The most exciting aspect of this is
when you see one of your projects deployed
and working, with a happy customer. When
your customer gets promoted you know that
the system worked well.”
Ponsford graduated with distinction from
Plymouth Navy College (UK). He earned a
bachelor’s degree with first-class honors in
Maritime Technology from the University of

The Raytheon Solution for Wind
Turbine Interference
Over the past two years, under contract
to the U.K. National Air Traffic Services
(NATS), Raytheon has developed a solution
to the wind farm interference problem for
ATC radars — one that cures the problem
instead of masking it. This solution relies
on four major enhancements in the PSR
signal processing chain that help the radar
differentiate valid aircraft returns from
false turbine returns. The solution has been
incorporated into a prototype radar modification kit that was fielded and tested over
extended time intervals at three Raytheon
ATC radar sites located in dense wind turbine environments. These tests produced
consistently excellent results (high detection
probability and low false alarm rate).
The processing enhancements (Table 1)
span the full extent of the radar data processing chain. The first key enhancement is
the simultaneous processing of data from
multiple receiver beams to improve the
probability of detection. In a traditional PSR
design, radar processing uses returns from
one antenna beam feed for near-range
processing, and then transitions to a second
beam for far-range processing. This transition facilitates ground clutter rejection for
near-range targets while maximizing energy
on target for distant objects. Raytheon has
demonstrated that by processing data from
both beams throughout the instrumented
range of the radar, and optimally combining
detection information from the two data
streams, significant performance gains can
be achieved, especially in high-clutter areas.
The second key enhancement involves advances in the real-time characterization of
the local radar clutter environment. PSRs
typically generate and continually update a
clutter map of the imaged space. This map
represents the strength of radar returns in
any given range/azimuth cell from stationary objects. The prevailing clutter levels in
a given area are used to establish detection thresholds such that when detection
thresholds are exceeded, a high likelihood
exists that a target is located in the area of
interest. The Raytheon wind farm mitigation
radar upgrade extends this technique to
characterize not only clutter from stationary objects, but also clutter from moving
objects such as wind turbine blades. By
doing so, many more appropriate detection thresholds can be produced for cells
containing wind turbines, which, in turn,
dramatically reduces false detections caused
by turbine blades.
The third processing improvement also
relates to the calculation of better detection thresholds. Part of the calculation to
establish a detection threshold for a range/
azimuth cell involves generating an estimate of not only the clutter level at that cell
location in the recent past (as referred to
above), but also the noise and clutter level
in the near vicinity of the cell at the present time. This component of the detection
threshold calculation can be thrown off by
the proximity of a wind turbine to the cell
of interest; the returns from the turbine
can bias the detection threshold to a detrimentally high level. This results in the radar
becoming desensitized in the vicinity of
wind turbines, losing the ability to identify
small targets in these areas. The Raytheon
solution detects and suppresses the influence of strong reflectors, in particular wind
turbines, to significantly reduce the desensitization of the radar in these areas.
The final enhancement provides powerful
mitigation effects at the back end of the
radar processing chain. Drawing from extensive experience in the tracking of small
targets in high-clutter environments for
maritime and over-the-horizon applications,
Raytheon has developed a sophisticated
Feature
Wind Farms
target tracker that forms a final line of
defense against wind turbine interference.
Based on both live real-time radar target detections and a priori information about the
radar environment, this tracker intelligently
identifies areas of high clutter and high
wind turbine activity, and then modifies
processing algorithms to maximize the likelihood of preserving real targets and rejecting
false ones. As an example, the near proximity of a wind turbine may cause the PSR
tracker to require additional corroboration
(e.g., additional detections in subsequent
radar scans) before declaring a valid target,
or to tighten up the boundaries within
which a target echo can be associated with
a track. The tracker also simultaneously
maintains multiple models of target characteristics for each tracked target, and based
on error measurements, combines the
outputs of these models in a statistically optimal way to yield a more accurate estimate
of target position and velocity than is possible with conventional tracking algorithms.
Field Test Results for the
Raytheon Solution
In 2010–2011, Raytheon’s wind farm mitigation kit was installed at three active ATC
radar sites in close proximity to large wind
turbine farms in the U.S., Holland (Figure 1)
and Scotland. The site in Holland had more
than 1,450 wind turbines within the instrumented range of the radar, while the
Scotland radar illuminates Whitelee, the second largest capacity wind farm in Europe.
Typical performance test results at these
sites, located directly over dense wind farm
areas with and without mitigation, are summarized in Table 2. In each case, radar
probability of detection was below acceptable specifications without mitigation, but
was improved to well above specification
with mitigation. Typical ATC customer specifications require a probability of detection
of 80 to 90 percent.

identified as Track A and Track B, are highlighted in Figure 2.
Deployment of the Raytheon Wind Farm
Mitigation Solution
The Raytheon wind farm interference mitigation solution is now in the deployment
phase. The first production deployment
modification kit was installed for the Royal
Netherlands Air Force at Woensdrecht Air
Force Base in Holland in the summer of
2012. Four additional systems are expected
to be fielded in Holland in 2013, and discussions are under way with defense and civil
aviation agencies in numerous countries (including the U.S., U.K. and Canada) for
upgrades and new radar system installations.
Four live radar demonstrations of this technology are being conducted at ATC radar
sites in the U.S. for the Federal Aviation
Administration and the U.S. Departments of
Defense, Homeland Security and Energy.
The Future of ATC Radar
and Wind Energy
Having successfully proven this technology
at Woensdrecht Air Force Base, Raytheon
is preparing to deliver it in newly deployed
PSRs as an upgrade kit to already installed
Raytheon radars, and even (in limited form)
as an add-on to third-party ATC radars.
Raytheon is building upon the success of the
wind farm solution by adding concurrent
weather radar processing capabilities, with
plans for deploying mitigation-equipped
systems to extend the solution to new application areas throughout this decade and
beyond. This is expected to relax the current
restrictions on the expansion of alternative
energy initiatives, while improving flight
safety and facilitating air travel. •

Figure 1. The AutoTrac III system is fully adaptable and scalable to any air traffic management environment.
The AT3 system is made up of management
and functional components distributed
across a network of servers and workstations. The components are all controlled
and monitored using standard Simple
Network Management Protocol (SNMP).
The management components process
fundamental system artifacts such as tracks,
flight plans, aeronautical and meteorological data, airspace and resources, and are
typically configured in a hot/standby redundant server pair architecture. The functional
components deliver capabilities to the different users (air traffic controllers), such as
situational awareness and tactical and planning tools, via a highly configurable display
component and human machine interface
(HMI) running on the workstations.
The system architecture and middleware
support multiple layers of redundancy that
provide the users with enhanced availability and safety. The hot/standby servers
and workstations are interconnected via
dual LANs. Failure of one server or one
LAN is transparent to the user. In the
unlikely event of a failure of both surveillance managers or both system LANs, the
workstations are also connected to an
independent third LAN and surveillance
manager to allow for the continued display
of surveillance data (tracks).
Flight data objects based on the flight plan
data are distributed to all workstations by
the flight data manager and can be used to
display extrapolated tracks in the total absence of surveillance data. The workstations
are also designed to provide continued
autonomous flight data operations in the
absence of the flight data managers. The
middleware also allows the user to logically
divide the system into two separate partitions temporarily — this is extremely useful
for providing uninterrupted 24/7 operations
while introducing a new software build
“on the fly.” For complete contingency/
backup purposes in the event of total system or facility failure, the AT3 middleware
also supports the ability to keep flight data
synchronized in real time across two independent systems.
Surveillance Manager
The surveillance manager fuses all sources
of surveillance data into a single integrated
display of tracks to provide maximum situational awareness for the controller. In
addition to traditional radar inputs, the
surveillance manager processes enhanced
Mode S, Contract and Broadcast-based
Automatic Dependent Surveillance (ADS-C
and ADS-B) and multilateration inputs. The
surveillance manager employs a front-end
processor to convert surveillance inputs into
industry standard formats to facilitate expansion and the addition of future inputs.
AutoTrac III
Feature
As an alternative to using AT3’s multi-sensor fusion tracker, the surveillance manager
can be configured to support the import
of system tracks using industry standard
protocols from an external tracker, if preferred by the user. AT3’s tracker can then
be used as a backup to the external tracker.
For enhanced situational awareness, AT3’s
surveillance manager can also export its system tracks to other external systems using
standard protocols.
The surveillance manager provides highly
adaptable safety net processing for monitoring all systems tracks to ensure that
appropriate separation is maintained between tracks and surrounding terrain and
reserved/restricted airspace. Additional
safety nets to monitor conformance to predefined approach and departure paths have
also recently been added to AT3. Any predicted or actual violations of separation or
conformance are presented to the controllers in a clear and unambiguous manner.
Raytheon’s surveillance manager is used
throughout the U.S. National Airspace in the
Standard Terminal Automation Replacement
System (STARS) and Enroute Automation
Modernization (ERAM) automation systems.
This same surveillance manager is used in
our AT3 system, ensuring global consistency
in the way aircraft are tracked and managed
by air traffic controllers worldwide.
Flight Data Manager
The flight data manager manages flight
plans, flight states, clearances and 4-D
trajectories. The heart of Raytheon’s next
generation ATM system’s advanced capabilities comes from its highly accurate
4-D trajectories. Trajectories are calculated
and maintained in World Geodetic System
(WGS-84) global coordinates using aircraft
performance data, surveillance data and
4-D meteorological wind and temperature
models. Trajectory information is distributed
internally and is also published to clients
based on European standards for trajectorybased operations. Examples of clients
making use of this trajectory data are Arrival
Management (AMAN) and Electronic Flight
Strip (EFS) systems. In the past, customers
had used such systems in a standalone,
non-integrated manner. Now AT3 provides
an architecture that enables these systems
to operate fully integrated. The use of electronic flight strip data by AT3 allows users
to transition from the traditional paper system to a more advanced, efficient and safer
paperless system.
The 4-D trajectories provide the foundation
for advanced tools and capabilities such as
Medium Term Conflict Detection (MTCD)
with a “what if” probe feature to enable
better strategic planning of the airspace and
various conformance monitoring aids to
alert the controller to any significant deviations of the aircraft from its trajectory.
The flight data manager is also sensitive to
Performance Based Navigation (PBN) and
Reduced Vertical Separation Minima (RVSM)
capabilities of the aircraft to further optimize the safer and more efficient use of the
airspace for both controllers and airlines.
Based on how an aircraft is equipped, the
system will allow for different separation or
routing criteria to be applied.
User Interface and Support Functions
AT3’s functional components provide the
user interface to the system. AT3’s user
interface (or HMI) is highly configurable,
based on the role and pre-defined privileges
of the different users. A major advance in
the AT3 HMI is that it is now very intelligent
and interactive. All the data a user needs
to perform their function is readily available
through a “heads up” display that allows
the user to focus on the traffic rather than
on a keyboard. The various display artifacts
allow on-screen interaction through mouse
and point-and-click type actions. Users are
no longer constrained to perform certain
functions at certain positions and have access to a rich toolset to make their tasks
safer, more efficient and, in some cases,
more automated. The advanced HMI also
provides capabilities for controllers to communicate “silently” with each other and
with other external systems, through electronic data exchanges, whereas in the past
a lot more verbal/telephonic communication
was required.
AT3’s support functions include an integrated simulator that generates simulated
surveillance, flight plan and meteorological
data for use by the management and functional components to provide a high-fidelity
replication of the operational environment
for an advanced training experience. The
support functions also provide pseudo-pilot
capabilities, which allow users to act as an
aircraft pilot, maneuver aircraft and talk to
student controllers. In addition, the system
supports an auto-pilot feature and voice
recognition capability, which allows the
system to be used for training without
always needing the support of the pseudopilot personnel.
As an enhancement to the overall training
experience, AT3 also offers an interactive
Computer Based Training (CBT) package,
which allows students to self-train and
familiarize themselves with the capabilities
of the system. The CBT package can also
be linked into COTS Learning Management
Systems to support the development of
training packages and student assessments.

T
he Multi-Spectral Targeting System (MTS) has been developed by Raytheon to meet the demand for high-quality
intelligence, surveillance and reconnaissance (ISR) at the
strategic, operational and tactical levels. The turreted “ball” incorporates visible, infrared and laser-ranging capabilities. Contained
within its limited volume is a full-featured sensor suite that provides
long-range surveillance, target acquisition, tracking, range-finding
and laser designation for the AGM-114 Hellfire missile and for all
tri-service and NATO laser-guided munitions. The MTS is deployed
globally on a wide variety of platforms, including the U.S. Air
Force’s MQ-1 Predator, the larger MQ-9 Reaper, the U.S. Army’s
Grey Eagle Common Sensor Platform, MH-60R and MH-60S helicopters, and manned fixed-wing aircraft such as the C130.
The MTS-A and MTS-B variants form the backbone of the MTS
family, incorporating advanced cameras, laser rangefinders/designators and gimbal control. The sensor can operate day or night.
MTS-A is the smaller, lighter ball, while MTS-B is a larger aperture
ball for improved resolution, longer range and better performance
(Figure 1). Some key parameters of the two balls are shown in
Table 1. The sensor offers multiple imagers, multiple fields of views,
and optionally, multiple laser sources. Advanced gimbals are used
on the turrets to provide highly stable platforms for both imaging
and lasing. The MTS-A uses a two-axis gimbal design, while MTS-B
uses a five-axis gimbal design to provide the stability necessary to
accommodate its higher-altitude operation and resolution.

faces the viewer. Other apertures are for alternative field of view and
lasing applications.
International Applications
The global market is growing as the need increases for both overland and maritime surveillance capabilities. Raytheon provides a
complete ISR solution that outperforms other turreted balls. The
U.K. has deployed Raytheon MTS products on Royal Air Force
Reapers. These have flown missions totaling more than 25,000
hours from Kandahar airfield in Afghanistan since their introduction in 2007, controlled by a contingent based at Creech Air Force
Base in Nevada. Raytheon also supports multiple operations for the
Italian Air Force with both Predator (MTS-A) and Reaper (MTS-B).

The Raytheon MTS family of turreted sensors
represents some of the most sophisticated
sensors available today. Combining precision
gimbal control, advanced optics and cameras, and advanced lasers, a single MTS turret
can support multiple applications, including
surveillance, targeting, tracking and reconnaissance. Systems currently employ high-definition visible and IR
sensors. Future, more advanced products will include more powerful lasers, improved sensitivity, accurate geo-location tagging,
improved on-board processing and additional spectral coverage.
These airborne sensors, hosted on unmanned aircraft, helicopters
and fixed-wing manned aircraft, will continue to offer worldwide
solutions that provide our warfighters and our allies the actionable
information needed to dominate the 21st century battlespace. •

Patriot
Patriot remains the most advanced combat-proven ground-based air and missile
defense system fielded in the world. It is
the backbone of Integrated Air and Missile
Defense for the U.S. and its allies. It is designed to be interoperable with the THAAD
(Terminal High Altitude Area Defense) missile system, the Hawk missile system and
other systems employed by our coalition
partners. Modernization through the incorporation of new technologies has enabled
Raytheon to evolve and grow the capabilities of this fielded and widely deployed
system to defeat advancing threats. As a
result, the U.S. government commitment to
Patriot has been extended to 2040.
Combat-proven during Desert Storm and
Operation Iraqi Freedom, Patriot has completed greater than 2,500 target search-andtrack tests across the entire range of its performance envelope. In addition, more than
600 highly successful missile firings have
demonstrated Patriot’s performance against
the full range of aircraft, tactical missile,
ballistic missile and cruise missiles threats.
Reliability of Patriot systems deployed
worldwide (measured in “mean time between failure”) remains more than twice
the required system specification.
Patriot Modernization
A comprehensive development program
to address parts obsolescence and to incorporate new technology upgrades was
initiated in 2008 to support a new production build of Patriot fire units for an
international partner. Although Patriot had
received substantial performance upgrades
to address evolving threats since its initial
fielding, it had been more than 12 years
since complete systems were produced.
Modernization has refitted Patriot with an
open, modular architecture. This includes
significant upgrades to the command and
control shelter, man stations, peripherals,
Internet protocol (IP)-based communications
and the radar data processor. In addition,
more than 1,000 existing PAC-2 missiles
have been upgraded to the current GEM-T
configuration to add the desired increase in
capabilities against advanced threats.
Part of Patriot’s ECS, the Patriot Modern
Man Station (MMS) operator-machine interface is used to identify and display airborne
objects; track potential threats; and engage
hostile targets, including aircraft, unmanned
air vehicles, cruise missiles and tactical ballistic missiles.
This modernized system, with its color
graphical user interface (GUI) and touchscreen display (Figure 2), gives the operator
significantly enhanced visual cues for identification of targets and priority alerts, and
it greatly improves battlefield situational
awareness with best-in-class command and
control decision-support tools. The new

The RDP is a major upgrade to the radar
set, replacing discrete analog and digital
signal processing components with a ruggedized commercial off-the-shelf processor.
The new RDP increases the reliability of the
digital processing system and related analog
components by 10 fold, resulting in a predicted 40 percent increase in overall radar
reliability. More importantly, it enables future capabilities through software upgrades,
including digital sidelobe cancelling, organic
combat identification, improved target
detection, multifunction surveillance and
the full support of advanced PAC-3 missile
enhancements.

improve radar multifunction performance, determine tactical ballistic missile impact and launch points, and provide interfaces with
the Terminal High Altitude Area Defense System. Remote launch
improvements increase the location of launchers from the ECS to
dramatically expand Patriot’s defended area.
Lockheed Martin develops and delivers
the initial PAC-3 missiles incorporated
into the Patriot system. The PAC-3

Into the Future
During the long 45+ year history of Patriot,
the modularity and flexibility inherent in its
original design allowed the Patriot system
to be upgraded and remain one or more
steps ahead of the threats. Future modernization efforts will further expand Patriot’s
capability in the areas of target detection,
engagement envelope and defended
volume. Furthermore, improved warfighter
effectiveness and reduced manning demands are enabled through automated
decision aids and role-selectable command
and control.
With a long history of successful deployments,
evolutionary improvements, recent modernization and the support of its growing list of
partner nations, Patriot is ready to provide
protection from emerging threats to the U.S.
and its allies through 2040 and beyond. •

tandard Missile, which first entered
production in 1967 as SM-1, was developed as a replacement for the Terrier,
Talos and Tartar surface-to-air missiles. For
50 years, Standard Missile technology has
evolved from that beginning to keep pace
with new threats and growing missions.
Phase 1 in 2011 included the deployment of
existing Aegis BMD-capable ships equipped
with proven SM-3 Block IA interceptors.
In March 2011, the United States sent the
USS Monterey to the Mediterranean Sea
to begin a sustained deployment of Aegis
BMD-capable ships in support of the EPAA.
On September 17, 2009, President Barack
Obama announced the U.S. decision to
adopt a new approach to ballistic missile defense in Europe. This plan, called
the European Phased Adaptive Approach
(EPAA), uses Raytheon’s Standard Missile-3
as a proven, cost-effective way to protect
our NATO allies and U.S. forces stationed
in Europe against ballistic-missile threats.
Raytheon is developing multiple variants of
SM-3™ (Blocks IA, IB and IIA) as part of the
Missile Defense Agency’s sea-based Aegis
Ballistic Missile Defense (BMD) System.
Phase 2 in 2015 will employ the more
advanced Block IB version of the SM-3 interceptor. Block IB maintains the reliability
of the Block IA variant while incorporating a
new two-color infrared seeker, an advanced
signal processor and a new Throttleable
Divert and Attitude Control System
(TDACS), providing the precision propulsion
necessary to intercept incoming ballistic missiles with pinpoint accuracy.

successful SM-3 intercept. During the test,
the target launched from the Pacific Missile
Range Facility on the island of Kauai. The
USS Lake Erie’s SPY-1 radar acquired and
began tracking the target. Several minutes
after target launch, the ship’s crew fired an
SM-3 Block IB. During flight, the missile’s
kinetic warhead acquired the target with
its two-color infrared seeker and tracked it
through intercept. Commonly referred to as
“hitting a bullet with a bullet,” the SM-3 is
designed to destroy incoming threat missiles
by colliding with them. This collision’s kinetic energy was the equivalent of a 10-ton
truck traveling at 600 miles per hour.
For Phase 3 in 2018, a significantly more
advanced SM-3 Block IIA interceptor is being
jointly developed by Raytheon and Mitsubishi
Heavy Industries (MHI) in Nagoya, Japan. The
partnership began with a 1999 agreement
among the Government of Japan, the U.S.
Missile Defense Agency, Raytheon and MHI
to operate as an integrated team to develop
Block IIA. Japan already deploys Block IA on
its Kongo-class destroyers.
MHI will provide Block IIA’s bigger secondand third-stage rocket motors. Raytheon
will furnish the advanced kinetic warhead,
which combines larger seeker optics, a 512
x 512 focal-plane array and an advanced
signal processor to improve both clutter
discrimination and target-acquisition range.
These enhancements will enable a single
ship to defend a wider region and destroy a
broader range of ballistic missile threats.
SM-3 continues to evolve as a critical resource in the ballistic missile defense of the
U.S. and our allies as it counters increasingly
sophisticated threats. •

Guided Intercept Validates Raytheon Evolved Seasparrow
Missile’s Role in Medium-range, Ground-based
Air Defense
NASAMS and Hawk Life Cycle Improvements
R
aytheon and our Norwegian
partner Kongsberg Defence &
Aerospace (KDA), with the
cooperation of the Royal Norwegian
Air Force (RNoAF), achieved an important milestone the spring of 2012
with the successful intercept and destruction of an airborne target with a
guided flight firing of the Evolved
Seasparrow Missile (ESSM™) by the
National Advanced Surface-to-Air
Missile System (NASAMS). The intercept (Figure 1) was part of an
ongoing effort by Raytheon and KDA
to increase the capability and flexibility of the NASAMS, Hawk and
Hawk XXI systems.
The ESSM missile is produced by
Raytheon and industry partners
from member nations of the NATO
SEASPARROW Consortium. The ESSM
missile provides NASAMS with the
proven capabilities of a ship-based
air defense missile in a groundbased system. ESSM is the third
Raytheon missile to be successfully
fired from the NASAMS common
rail launcher, following the AIM-9X
Sidewinder firing in 2011 and the
Advanced Medium Range Air-to-Air
Missile (AMRAAM), which has been
deployed with the NASAMS system
since its initial operational capability
in 1994 (Figure 2).
The NASAMS system, jointly developed by Raytheon and KDA, provides
a state-of-the-art medium range
air defense system that can quickly
identify, engage and destroy current and evolving enemy aircraft,
unmanned aerial vehicles and cruise
missile threats. Fielded in Norway for
more than a decade, the RNoAF has
operated NASAMS as the cornerstone
of their airbase and their high value
asset defense. The RNoAF continues
to modernize the system through a
robust system life cycle management
program. Recently, the Norwegian
Defence Logistics Organization contracted Raytheon and KDA for a
modernization program that includes
command and control upgrades as
well as the addition of Raytheon’s
High Mobility Launchers to RNoAF’s
existing canister launcher fleet.
NASAMS is also operationally deployed in the U.S. National Capital
Region, Spain and the Netherlands;
and an initial operational capability is
planned in Finland in 2015.
The guided flight test demonstrated
the potential for ESSM on both the
NASAMS and Hawk XXI systems.
Both the Hawk XXI and NASAMS
systems share a common architecture
today, including the Fire Distribution
Center (FDC) for command and
control and the Sentinel radar for
surveillance and tracking. During the
ESSM guided-flight demonstration,
the FDC used the Hawk High Power
Illuminator (HPI) radar (Figure 3) to
illuminate the target for the ESSM
semi-active guided intercept. For
Hawk customers, the ESSM firing
demonstrated the low risk of integrating the ESSM missile in the Hawk
XXI system. For NASAMS customers,
the ESSM missile offers additional
capability, and the choice of interceptors allows more flexibility in their
defense designs. The ESSM missile
also offers logistic and maintenance
savings for countries that already
use the ESSM missile for Naval air
defense.

The ESSM guided-flight demonstration consisted of the NASAMS FDC and launcher,
the Sentinel radar (tracking and cueing),
the Hawk HPI radar and the ESSM missile.
The firing demonstrated NASAMS’ capability to acquire and track a target, initialize
and launch an ESSM, cue the HPI, illuminate the target and guide the semi-active
ESSM missile to the intercept. The NASAMS
FDC’s capability to support the current
Hawk launcher, Hawk HPI radar and Hawk
surveillance radar provides an incremental
upgrade path for current Hawk customers
to keep existing assets while modernizing
the overall system.
In less than 10 months from concept
inception to the ESSM guided-flight
firing, the NASAMS team assembled experts
from across Raytheon and KDA to carry
out the development effort. Raytheon provided missile analysis, ESSM Naval missile
integration expertise, Hawk HPI radar support and the software modification to the
NASAMS launcher’s missile interface unit.
KDA provided modifications to the FDC fire
control to accommodate the ESSM performance. Due to the open architecture of the
NASAMS system, no other changes were
necessary to support the firing of the new
missile.
The team was successful in meeting the
aggressive development schedule. The
firing resulted in a direct hit by ESSM, witnessed by government representatives from
Australia, Chile, Finland, the Netherlands,
Norway, Spain, Sweden and the United
States.
The ESSM firing is an example of the international cooperation and extensive
customer support for the NASAMS system.
The firing would not have been possible
without the contributions of the Norwegian
Air Force, which provided most of the assets
and the test range for both the guidedflight test in May and the ballistic test
firing in March; the United States Security
Assistance Management Directorate
(SAMD), which provided the Hawk HPI
radar; and the SEASPARROW consortium,
which provided the ESSM missiles. The
ESSM guided-flight firing occurred during
the Norwegian Air Force’s annual live firing exercise of their NASAMS system at the
Andoya Rocket Range in Northern Norway.
In addition to the ESSM firing there were
four NASAMS AMRAAM guided-flight firings against drones, all with challenging
flight profiles.
The ESSM firing is just one example of the
ongoing effort to provide greater flexibility
and capability to our international air
defense customers, in addition to providing
a continually improving system ready to play
a greater role in U.S. defense. •

of an evolving worldwide threat
R
aytheon C4I system solutions support
the U.S. military and more than
60 international customers on six
continents, providing a total battlefield
integrated system-of-systems capability.
• Low-flying, slow UAVs and low-flying,
fast cruise missiles are serious and
proliferating threats.
Immediate threats to the security of sovereign nations vary based on the domain,
country or area within a country. There are,
however, the following trends:
• Asymmetric threats on land and sea are
growing at a rapid rate.
• Attack from many small, swarming boats
is an issue both for naval and commercial
vessels.
• Electronic warfare is evolving, increasing
its overall level of sophistication.
• Within the air and space domains, the
ballistic missile threat has expanded to
include rogue nations.
• Cyber warfare is proliferating at an
accelerating pace.
• Many nations are acquiring unmanned
air systems (UAS) intelligence, surveillance
and reconnaissance (ISR) platforms.
• Threats to position location, precision
navigation and timing systems (e.g., GPS)
are likely to have a more widespread
impact.

The ultimate goal of C4I systems (Figure
1) is to provide commanders with the appropriate and timely information they need
to address these threats. Towards this end,
Raytheon’s C4I systems have a wide range
of capabilities that enable:
• Development of a situation awareness
(SA) or common operational picture
(COP), and the sharing and displaying
of this picture as required by commanders at all levels.
• Efficient communication of tasking to
implement directions and decisions
among the command hierarchy in order
to support their forces in executing
operational plans.

Figure 1. Operational View of integrated air, land, maritime and joint C4I systems. Raytheon’s C4I solutions provide a total battlefield integrated
system-of-systems capability for the U.S. military and our international customers.
Feature
• Analysis of the operational environment to
automatically identify or support the manual identification of threats, and to provide
threat response guidance.
Underlying the above capabilities are tools
and support for comprehensive planning
across three distinct command authority levels
or echelons: strategic C4I (planning weeks
to years in advance by a national command
authority), operational C4I (planning days to
weeks in advance, by an operations center),
and tactical C4I (days to real-time planning,
down to the battalion level).
Raytheon’s C4I Capabilities
Raytheon’s C4I operational capabilities and
enabling technologies are summarized below.
Working in concert, these discriminators
provide the ability to obtain, gather, process
and distribute information to optimize datato-decision effectiveness, thereby enabling
defensive forces to respond promptly and appropriately to the constantly evolving threats.
Common Operational Picture (COP):
C4I provides a common operational picture
(COP) for situational awareness that can be
made available to all command elements.
Key capabilities necessary in developing this
picture include the ability to integrate track
and contact data from a host of sensors
types, and the correlation of that data to address multiple tracks due to sensor overlap.
It is typical for sensors to have various output
formats, periodicity, and error characteristics,
as well as other variables. Within each of the
C4I systems, the track management component, typically consisting of a specific number
of trackers and a correlator, reconcile these
differences to create an accurate integrated
picture. Additionally, C4I systems can include
non-track data that enhances the track picture
(information specific to a commercial vessel
or airliner, for example). Raytheon has long
been a leader in the technology behind trackers, which are enablers for several Raytheon
C4I products, including the Advanced MultiSource Tracker (AMST) used in Sentry® and
the Solipsys Multi-Source Correlator Tracker
(MSCT [domestic] and MSCT-I [international]
version).
Raytheon Tracker Technology for C4I
A prerequisite to the development of a COP is the ability to accurately track forces
regardless of domain. Raytheon has developed a number of general purpose and
specialized trackers that are the workhorses behind our leading C4I systems. During
tracking, the system must associate multiple source plots with a track, and then smooth
associated plots to estimate the target state in terms of position and velocity. The tracker
must account for targets in close proximity, tracking in two and three dimensions, highG maneuvers and clutter around a target. Different trackers can use different techniques
to develop and maintain a track. Typical among these are statistical data association,
dynamic clutter mapping and track branching (see Figure).
The tracking process typically starts
with Automatic Track Initiation (ATI).

(beacon) plot messages representing
the same target to initiate and maintain a single local track.
Raytheon trackers improve track continuity and accuracy using statistical data association
methods for both active and passive (jamming) data, a variable update filtering schedule,
Sequential Probability Ratio Testing (SPRT) for track initiation, and an Interacting Multiple
Model (IMM) filter for track state estimation.
IMM uses multiple Kalman filters running in parallel to represent different potential maneuver states of the track. This enables the system to continue tracking highly evasive
targets through high-G and high-speed maneuvers. When the plot-track association
probability falls below the confidence level, track branching (two or more tracks that
represent different hypotheses about the target’s motion) revises the decision based on
subsequently processed radar data. A probability is calculated for each branch, based on
correlated plot data. A branch is deleted if its probability falls below an adapted threshold. The most probable branch is made available for display and other system functions.
Sensor registration computes and applies corrections to sensor data to compensate for
atmospheric and other biases that affect the accuracy of that data in a systemic and
repeatable way. Collimation computes corrections to range and azimuth needed to
align a radar with its secondary (beacon) returns. Using a real-time, on-line algorithm,
the system estimates and applies radar registration and collimation bias corrections. This
reduces the effect of radar measurement bias errors, minimizes duplicate tracks and improves track accuracy. Together, SPRT track initiation, the multiple branch approach, the
IMM filter, and automatic measurement bias estimation and removal provide superior
tracking performance against small targets, maneuvering targets and targets in clutter.
Feature
C4I Systems
Situation Analysis: The ability to employ
threat recognition capabilities directly in the
C4I system for threat behaviors as they are
identified offers an additional level of analysis for watchstanders and commanders.
Several approaches to situation analysis are
included in Raytheon C4I systems, including
rule-based analysis of kinematic or track details, analysis of historical data and analysis
of other related data. Examples of these
approaches include:
• Automatic identification (e.g., pending,
unknown, assumed friend, friend, neutral, suspect or hostile) based on either
direct information through identification
friend or foe (IFF), blue force tracking,
automatic identification system (AIS) information and/or selective identification
feature (SIF) code.
automation reduces the response time
for completing a task, ensures that proper
approval has been granted and offloads the
coordination of the process from the staff,
providing more time for operational
activities.
Enhanced Mission Planning: Raytheon
C4I systems provide operational planning
for different command echelons within a
single service branch, across multiple service
branches, and for both military and civilian
agencies. This includes status information
on systems, equipment and personnel that
can be entered into the system and then
automatically distributed to commanders of
other units, services or agencies.
This analysis of track data and enhancement data by the system can bring to light
information not readily discernible by a
watchstander or commander. As threats
evolve, Raytheon C4I systems allow appropriately trained customer personnel to
modify the parameters of threat identification algorithms to counter new threats.
Effective planning involves processing large
amounts of information. This is enabled
by work areas that provide a single, multipanel window displaying the most accessed
information in a concise manner while also
providing access to less commonly used
data. Operator actions are minimized by
automatically linking selected data to other
related panels. Operator efficiency is also increased by anticipating common behaviors,
by automatically populating data entry fields
and by performing tasks (such as creating
a mission) based on the context of the operator’s actions. An associated interactive
graphics information system (GIS) display
provides a graphical representation of a
work area’s information, enabling visual,
graphics-based updates for the many planning tasks. As entered updates appear on
the GIS, the changed data automatically appears at corresponding locations within the
appropriate work area.
Guidance for Threat Response:
Raytheon’s C4I systems are easily adaptable to seamlessly support a customer’s
unique workflows and doctrines within
a system’s perimeter. For example, when
a threat is observed and entered into the
system, the workflow capability guides operators through the additional data entry,
evaluation processing and approval screens
necessary for an appropriate response. This
Raytheon’s multilingual capability makes a
complex system easier to use by operators
of different nationalities. Internationalization
software performs text replacement with
the appropriate lookup translation in the
customer’s language; and, for the Middle
East and other parts of the world that use
right-to-left language flow, the C4I software properly translates the screen layout
and data sequence accordingly.
• Threat identification based on track characteristics and other kinematic data such
as penetration of restricted areas, exceeding specific altitudes/speed criteria for
specific types of tracks, maneuvers not
typical for specific track types, and impossible movements or threat launch point.
• Use of reference databases to identify possible spoofing of identification beacon information (such as a ship previously
reported as “scrapped” showing up in
the COP).
Tactical Edge C4I Platform: Tablets and
smartphones are replacing ruggedized field
laptops for many applications, both civilian
and military. Raytheon’s C4I technology addresses several challenges to their effective
use, such as the security of devices and the
data transmitted, as well as the reliability
of network connections in hostile environments limited by low bandwidth and data
dropouts. Raytheon’s C4I solutions conserve bandwidth, detect and recover data
dropouts, maintain functionality even when
disconnected, and facilitate resynchronization when connectivity has been restored.
Composable C4I: Advanced C4I Systems
are modular within a common service oriented architecture (Figure 2). Composable
systems use functional components that
plug into an open, extensible framework
and become interoperable through the use
of standard rules of the framework services
that support messaging, data transformations and translations by way of publish/
subscribe design patterns.
An example of this is Raytheon’s Athena,
which is a multidomain situational awareness system with capabilities centered on
the maritime environment. Athena has been
deployed in more than 20 locations around
the world as a stand-alone product.
In one instance, a Raytheon customer
requested a solution that would require
a blend of Raytheon’s Command View®
military C4I system planning and battle
capabilities and Athena’s maritime domain
awareness capabilities. It took the program
team very little time to develop a solution that leveraged the capabilities of both
products in a far quicker and cost-effective
way than re-developing those capabilities as
stand-alone products. This was enabled by
the Command View and Athena systems’
open architectures that allowed for a rapid,
efficient, and cost-effective integration of
new capabilities.

Figure 3. Raytheon’s Integrated C4I Solution. Command View C4I capabilities are available
to different command echelons within a single service branch, multiple branches, and military
and civilian agencies.
Raytheon C4I System Solution
Examples
Two examples of Raytheon’s many C4I
system solutions that have a strong
international presence are Command
View — an integrated and scalable military
C4I system, which has air, land, naval
and joint applications for operations
mission planning and tasking at the strategic and operational levels; and Sentry
— the world’s leading real-time air situation awareness and mission execution
system, predominantly operating at the
tactical level.
Raytheon’s Command View is a fullfeatured C4I system, supporting joint,
combined and component operations at
the higher-level strategic and operational
echelons, and providing capabilities for
military operation planning, execution
and monitoring (Figure 3). Its flexible
design enables the system to effectively
synchronize military actions through
network-centric operations. Employing
a service-based, layered architecture,
Command View is scalable to meet any
size requirement. It can run on a variety
of platforms and is adaptable for future
growth and evolution. Command View
provides operators with a multilingual
user interface, multiple decision aids and
a consistent set of features. It includes
adaptable processes that can integrate
with existing systems, and it allows for the
incorporation of factors and conditions
such as operating doctrines and procedures. Variants of Command View are
located in 16 nations around the world.
An air application of Command View,
developed by Thales-Raytheon Systems
(TRS), a joint venture between Raytheon
Company and Thales Group, is integrated
in NATO’s largest software system —
the Air Command and Control System
(ACCS). Initial deployment of five NATO
ACCS sites is currently underway in
Belgium, France, Germany, Italy and the
Netherlands, and will be followed by
Feature
C4I Systems
sites in additional NATO countries for a total
of 17 operational European locations. ACCS
provides comprehensive air battle planning
and execution resources at the operational
level. It includes situation awareness, force
development, plan development, targeting,
current operations monitoring, planning
and management of air operations, airspace deconfliction, air-to-air refueling,
weapons tasking, command and control
(C2) and order of battle resources. Similar
capabilities have been tailored for land
and joint domains by optimized Command
View variants. ACCS is standards-based,
being fully compliant with the NATO C3
Technical Architecture (NC3TA) and the
NATO Architecture Framework (NAF). ACCS
includes planning work areas, which provide
optimal operator workflow by harmonizing common data and tasks into a single
display that interacts with the GIS. A current
enhancement is extending ACCS to support
ballistic missile defense as part of NATO’s
Active Layer Theater Ballistic Missile Defense
Program.
Command View Mobile provides
C4I displays and secure voice and
data communications over existing
cellular networks. Command View
Mobile provides a simple, lowcost executive information system
(EIS) at any echelon as well as to a
mobile C4I capability for selected
operations at the tactical network
edge (Figure 4).
Sentry provides a consolidated air
picture with combat identification
for positive control and increased
situational awareness (Figure 5).
Sentry integrates multiple radar/sensors
(such as long-range surveillance radars,
short-range battlefield radars and gap-filler
radars) correlated with civil and military
flight plans and a rich set of tactical data
Figure 4. Command View Tactical and Mobile platforms support the command center
and its soldiers at the tactical network edge
over both tactical radio and cellular networks.
Command View Tactical is a C4I software application integrated into multiple
networks and vehicles. It combines movement and maneuverability, intelligence,
mission command, sustainment and protection capabilities into a single, intuitive,
soldier-operated, Windows-based computer
application. It is easily configured for Tactical
Operations Centers (TOCs) from platoon
through division levels, and it can adapt to
a large range of communications media. A
unique feature of Command View Tactical
is that it is designed to operate within the
limited bandwidth and network reliability of
today’s tactical communications networks
(e.g., Combat Net Radio networks).
Figure 5. Sentry enables real-time tactical air mission execution. Sentry is the core of the USAF
Battle Control System, defending North America from air attack. It is also used by many other
nations around the world.
Feature
links to provide surveillance for acquiring,
tracking and identifying aircraft in low-,
medium- and high-clutter environments.
Sentry also provides threat evaluation and
weapons assignment, interceptor control,
surface-to-air missile control and an automated flight advisory function for operators
controlling aircraft. The U.S. Air Force now
uses Sentry as their primary situational
analysis tool at the air operations command
level. It is deployed to 24 nations around
the world.
Raytheon’s technology enabling solutions continue to meet the increased
demand for robust C4I systems, in order
to remain one step ahead of an evolving
worldwide threat. High-value assets, such
as aircraft, ships, tanks, ambulances and
emergency response vehicles are expensive to acquire, operate and replace; yet
they are put in harm’s way in everyday
operation. Raytheon’s C4I systems enable
organizations to employ their assets more
effectively and economically, achieving a
force-multiplying effect. Modern C4I systems leverage advanced communications
technologies to harness “the power of the
network.” These solutions are integrated
for enhanced collaboration and situational
awareness across all levels,
and Raytheon continues to develop and
improve these capabilities for our
customers. •

aytheon Solipsys has established itself as one of the industry leaders in tactical
command and control in recent years, deploying systems across multiple U.S.
services and international placements. In August of 2012, Raytheon Solipsys
announced it had been awarded a contract through the U.S. Navy’s Space and Naval
Warfare Systems Command (SPAWAR) Code PMW-740 to provide a state-of-the-art
maritime surveillance system to the country of Montenegro. The turnkey Maritime
Information Management System (MIMS) is a sophisticated command-and-control capability providing enhanced situational awareness in support of maritime sovereignty and
security challenges. Built upon Raytheon Solipsys’ expertise in tracking and visualization,
MIMS integrates radars and other surveillance sensors, providing sophisticated decision

The Raytheon Solipsys operational maritime information system (MIMS) display provides
enhanced situational awareness through a correlated radar and automated identification
system (AIS) display with an electronic nautical chart (ENC) and satellite imagery underlay.
The system employs layered, multisensor integration and correlation to support the detection and identification of potential sea-based threats utilizing inputs from maritime
surveillance radars, Automated Identification System (AIS) receivers, GPS-based self-reporting devices, and other external data sources. All information is presented and
managed in real time on maritime display applications and web portals to various operators and government agencies. Intelligent decision aids automatically generate alerts and
responses for anomalous conditions, including intruder detection, unexpected vessel behavior, and other safety or security hazards. Operators can tailor or create new decision
aids to identify objects and recognize situations of concern as required. •

Advances in automated human language
processing technologies such as speech
recognition and machine translation have
opened up new capabilities in processing
traditional media forms such as broadcast
television and Web content. The GALE
program (Global Autonomous Language
Exploitation), funded by the DoD’s Defense
Advanced Research Projects Agency
(DARPA), focused on improving the state
of the art of automatic machine translation.
Numerous human language technology
development programs at the Combating
Terrorism Technology Support Office/
Technical Support Working Group (CTTSO/
TSWG) have transitioned these advances to
operational use. In 2003, the first operational, fully automated media monitoring
systems were deployed.
Multimedia Monitoring System
Raytheon BBN Technologies’ (BBN) commercial off-the-shelf Multimedia Monitoring
System (M3S) delivers an end-to-end capability for monitoring, translating, storing
and searching a wide variety of open source
media across a range of languages. M3S
provides users with real-time understanding
of news, events, and perceptions around
the world. The system can be configured to
process any combination of inputs
(i.e., analog broadcast, Web text, file-based
media) and support any number of channels
and users, giving English speakers direct
access to foreign language multimedia from
a single browser-based user interface.
Distributed Architecture
M3S is designed as a distributed Web-based
system that allows its components and services to be optimally located in proximity
to its media sources and human users. The
distributed design, shown in Figure 1, also
supports easy expansion, robust failure recovery and inter-agency data sharing.
M3S is delivered as a turnkey system, with
all hardware and software, and is composed
of the networked components described
below, which are also available as separate
turnkey offerings. Additionally, the core
analytics can be unbundled and integrated
into other third-party systems either at the
operational level or at the data level.
BBN Broadcast Monitoring
System™ (BMS)
BMS processes television and radio sources
to create a continuous, searchable, one-year
archive of audio/video and its associated
machine transcription and translation metadata for every channel. An audio stream
from ingested video is automatically processed through the BBN Audio Monitoring
Component (AMC), which is the core software solution. AMC includes an integrated
pipeline of advanced natural language
processing (NLP) technologies such as
speech recognition, speaker tracking, sentence boundary detection, named-entity
recognition, and machine translation. BMS
also includes BBN’s state-of-the-art optical
character recognition (OCR) component for
the automatic detection and transcription of
on-screen text in video images.
Figure 2 shows the home screen of the BMS
— the Channel Overview. This screen contains a search box, a list of persistent queries
(the watchlist), and a thumbnail overview
of the available channels. The overall application operates in real time, producing
content that is available for search no more
than three minutes after it is aired. BMS is
available in 15 languages, including Arabic,

The J2 Open Source Intelligence (OSINT)
group at the United States Central
Command (USCENTCOM) in Tampa, Fla.
has been using both broadcast monitoring and Web monitoring capabilities since
2004. Initially staffed solely with monolingual English-speaking analysts, this group
was tasked with reporting how foreign
media portrayed U.S. actions in the Middle
East. Since BBN multimedia monitoring
systems were deployed, the group has
increased their reporting from three short
products per week to more than a thousand
requests for information (RFIs) per year,
drawing information from open sources,
using linguists to enrich the translation and
to provide cultural background and insight.
Based on these successes, BBN’s media
monitoring solutions have spread to OSINT
groups at other combatant commands
(COCOMs) and the broader DoD.
BBN Web Monitoring System™ (WMS)
The WMS processes website sources, capturing content from user-selected websites
on a schedule specified by the user organization (Figure 3). The captured sites are
translated, archived and versioned for later
use, so there is always a local copy available,
even when the page has disappeared from
the active Web. Internal links are preserved
in the harvested Web pages so users can
navigate within the archived sites. English
speakers can obtain a basic understanding
of an ingested Web page by reading the
English translation automatically produced
by the Language Weaver MT software
(available in over 30 languages), then reach
through the network for human translation
support when a higher-quality translation
is desired.

Language Learning
Future Capabilities
The DoD devotes considerable resources to
teaching people to speak other languages,
and soldiers who have successfully mastered a second language are incentivized
to sustain their fluency. The creation of
current, authentic learning content for the
classroom is a laborious task, and instructors
may spend hours or days preparing a short
video clip for a single lesson. As part of an
effort funded by the Combating Terrorism
Technical Support Office (CTTSO), BBN
enhanced their broadcast and Web monitoring systems to act as a platform for rapid
content creation for language instructors.
Teachers can locate a clip about a particular topic or theme, use a built-in editor to
transform the media into lessons such as
fill-in-the-blank, matching or a flashcard set,
and distribute the lessons to students on the
desktop or a handheld device. These capabilities have been deployed at the Defense
Language Institute and other DoD and intelligence community learning centers.
The media monitoring suite of technologies
is now a platform for deploying new human
language analytics and technologies to operational users, as well as for applying them
to new and varied media types.
Automatic Topic Detection and Tracking
allows processed media assets to be
automatically labeled with human-readable
tags, and then grouped with other, similar
media assets. This allows analysts to rapidly
find content using a “more like this” style
of search.
Entity Profiles automatically build biographies of a person or organization from
open source information. Biographies might
include statements made by or about the

past/present affiliations. The profiles will
enable users to quickly discover new specific
facts, rather than dredging through unrelated content.

LEADERS CORNER
John Harris
President, Raytheon Technical Services Company (RTSC)
John D. Harris II is the president of Raytheon Technical Services Company
and is a Raytheon Company vice president. RTSC specializes in training,
logistics and engineering solutions for the mission support, homeland
security, space, civil aviation and counterterrorism markets.
In 2010, Harris received the Black Engineer of the Year Award. He serves on
the Radio Technical Commission for Aeronautics NextGen Advisory
Committee, the Board of the USO of Metropolitan Washington, D.C., the
National Advisory Council on Minority Business Enterprise with the U.S.
Department of Commerce, and he is a member of the Council of Trustees for
the Association of the United States Army.
T
echnology Today recently spoke
with Harris about Raytheon
Technical Services Company’s business, priorities and long-term strategies.
TT: What are your top priorities for RTSC?
JH: Our three keys to success are focus,
leverage and innovate. To excel in a
dynamic and volatile market, RTSC must
focus on our customers, leverage our
capabilities with existing and emerging markets and innovate for profitable
growth. Ultimately, executing on a path
to growth is a top priority — delighting
our existing customers with innovative
solutions and flawless performance, and
winning new customers.
As a business, we must constantly challenge ourselves to learn the business, be
adaptable, and empower others for decision making. It is imperative to continue
educating on who we are and what we
do and facilitate sharing across RTSC, and
the enterprise, to expand our portfolio and
drive growth.
The top-line challenge around reducing budgets is an opportunity for RTSC
because we have proven to our customers
time and time again that we can bring new
ideas to the table that cost less — we are
willing and flexible enough to try something new.
We offer solutions tailored to the specific requirements of our customers and
integrated tools and processes that equal
cost-saving solutions, while continuing to
invest to address customers’ current and
future needs. Listening to our customers
has helped us go beyond what we normally
do to innovate and create new and different products and services. I am nothing
less than amazed at the work that we do
at RTSC.
TT: Could you expand upon the three key
areas of RTSC’s business: training, logistics
and engineering solutions?
JH: RTSC provides defense, government
and commercial customers with mission
support across all domains, including
integrated training solutions; logistics and
product support; engineering solutions;
homeland security, counter-proliferation
and counter-terrorism solutions; and
range operations. Our three primary core
competencies are training, logistics and
engineering solutions.
RTSC is the world’s largest provider of fullservice learning solutions in our chosen
domains — we train more than two million
people every year. RTSC trains every U.S.
air traffic controller and Army soldier and
we train every technician and salesperson
for one of the world’s largest automotive
manufacturers.
As one of the world’s largest providers of
mission-critical operations solutions in the
defense and civil government markets, we
have served customers on all seven continents plus the Arctic region. Our proven
systems engineering approach enables
us to handle the largest operational challenges cost-effectively and safely.
RTSC provides value-based and cost-effective upgrades to military systems in the
air, land and sea domains — total lifecycle
support across all domains. We have a
proven track record of transforming
operations and maintenance services to
dramatically improve efficiency and
reduce costs.
Our push is international, with four major
geographic focus areas including: North
America, the Middle East, Australia and
Europe. As the business looks ahead, we are
positioning for great efficiency and competitiveness. We are preparing our people for
tomorrow’s challenges. We are expanding
in core and adjacent markets. And we are
extending our global penetration and building capabilities to sustain growth.
In all these ways and more, we are leading
the market, both domestically and internationally. I am very proud of our commitment
and performance.
TT: How does technology play into your
long-term strategy?
JH: Technology plays a key role in our longterm strategy. For example, RTSC is working
with the commercial industry to bring the
latest 3D synthetic scene generation technologies to the warfighter to create a more
realistic training experience at home and
better situational awareness in the field.
For the field, our newest innovations and
products include smart displays for ground
vehicles designed with gaming industry 3D
graphic technology to allow for real-time
processing of high definition video and 3D
synthetic scenes to provide the finest tactical situational awareness displays available.
Other innovations include the use of
helmet-mounted displays to present 3D synthetic scenes to pilots and adding 3D audio
generation for a true multisensory approach
to increasing situational awareness. These
systems are designed to be easily installed
on platforms such as the F-16, which are
part of air forces around the world. For
helicopter platforms, we have developed
an Aviation Warrior product consisting of
a wearable computer linked to a display
device worn on the wrist, which allows for
situation awareness for the helicopter pilot
even after they disembark from the cockpit
— which is revolutionary.
A further example of an innovative software
engineering solution we’ve developed is
the Precision Real Time Location System
[PRTLS] for use at one of the U.S. Army’s
Combat Training Centers, the Joint MultiNational Readiness Center [JMRC]. PRLTS
provides a cost-effective option using commercial off-the-shelf [COTS] products and
existing Range Data Management Systems
[RDMS] infrastructure for instrumenting
large numbers of players to track positions
within the entire training area covered by
the site’s Instrumentation System. The JMRC
extended training area includes Hohenfels
and Grafenwohr, Germany.
Finally, in order to affect training transformation we have the Architect and Catapult
products. Architect is a powerful analysis
tool that applies a systems approach to
reengineer large-scale, highly-complex
training programs and curriculums. We
are currently using this with the FAA and
General Motors, as well as the Universal
Technical Institute. Catapult is a Learning
Content Management System that allows
our development teams to produce Webbased training and mobile learning courses
in reduced time, at lower cost and in
multiple languages.
TT: What are you doing to make RTSC
more competitive in today’s marketplace?
JH: As I mentioned earlier, in order to excel
in a dynamic marketplace we must focus,
leverage and innovate.
We must focus on our customer by aligning our business development team around
domains to be certain that we are offering our customers our best thinking across
capabilities, while being certain that we
raise our value proposition, moving from
a transactional approach to an enterprise
approach, to provide the best possible
solutions. Additionally, we must focus on
the regions in which we presently do business to see what other solutions we can
provide in the more than 80 countries in
which we operate.
We must leverage what we do in our offerings of training, logistics and engineering
solutions. How do we leverage the training
we do with the military to grow the civilian
training business in the healthcare arena,
and how do we leverage the training we do
with General Motors to improve our military
training? How do we leverage the logistics
work we do for our military customers to
attract new business from customers around
the world? And finally, how do we leverage
our engineering solutions offerings, such as
aircraft upgrades, to include more platforms
for our military customers and maybe find
civilian uses for these solutions?
Finally, we must innovate our practices,
our tools and our business structure to
remain lean and forward thinking. We must
challenge ourselves to constantly generate
and be open to new ideas, use collaboration
and remain positive to find those new solutions to our customers’ issues and explore
areas for new business development. •

Monitoring and Managing
Cybersecurity Events in Complex Systems:
A Multidimensional Approach
• Protect the systems and the data they
carry against cyberattacks, including recognition of the onset of a cyberattack in
a timely manner and with cost-effective,
threat-appropriate (cyber) protection and
mission or policy-appropriate responses.
Current attempts to overcome CS threats
include intrusion detection and prevention systems (IDS/IPS), firewalls and packet
scanning software.1,2 Individually, these
approaches are challenged to prevent or
provide sufficient countermeasures to
overcome and resolve the wide spectrum
of CS threats that affect the multiple and
diverse components that compose a
complex enterprise system.
To meet this need, Raytheon has proposed
a new multidimensional CS approach
to monitor, manage and respond to CS
events. This approach extends Raytheon’s
End-to-End Enterprise Monitoring
(E2E-EM) Reference Architecture,3 developed under the guidance of the Defense
Information Systems Agency (DISA), to
include a new response dimension that
activates countermeasures to prevent or

includes: the X dimension (measurement time intervals), which defines
time-based events; the Y dimension
(domains), which addresses events
that are detected and responded
to using similar techniques and
instrumentation; and the Z dimension (enterprise perspective planes),
which introduces structures within
which particular end-to-end events
are monitored and managed, possibly spanning multiple time intervals
and domains. The Cybersecurity
Plane, highlighted in red (Figure 1),
enables end-to-end, enterprisewide detection and response for

Planes
Figure 1. EMMRA CS is a multidimensional reference
architecture comprising three dimensions: domains to
account for traditional monitoring layers such as infrastructure, network and applications; enterprise perspective monitoring planes to account for enterprise
monitoring and management across these traditional
domains; and measurement time intervals to account
for response time to mitigate CS events.
EMMRA CS is realized using CS
agents that are deployed throughout the enterprise hardware and
software components (including IDS, IPS
and firewalls), where they continuously
monitor the enterprise system for CS metrics. Distributed agents have previously
been used to combat cyberattacks, such
as Distributed Denial of Service (DDoS).5,6
However, EMMRA CS adds a new collaboration capability called collection and
analysis nodes (CANs), which correlate the
CS metrics information collected by CS
agents to provide an end-to-end picture
across multiple, diverse administrative domains for security responders. The CANs
are distributed throughout the enterprise in
various operations (Ops) centers, according
to the domains of the EMMRA CS architecture, such that the missions they support
determine the CS agents they use and the
metrics they analyze. For example, Figure
2 shows a CAN located at the Local Ops
Center that could collect/analyze infrastructure domain CS metrics from distributed
EMMRA CS agents. Both the collected metrics and the analysis of these metrics would
then be stored in the Local Ops Center
database that could be exposed over the
enterprise system to authorized subscribers,
such as security responders and other Ops
centers. An authorized Regional Ops Center
could then subscribe to the published data
from the Local Ops Center’s CAN database
and collect/analyze additional applications domain CS metrics from distributed
EMMRA CS agents. Likewise, an authorized
Enterprise Ops Center could subscribe to
published data from Local and Regional Ops
Centers’ CAN databases and collect/analyze

Figure 3 shows a representative enterprise
system that includes strategic network components and interconnection points where
EMMRA CS agents can effectively observe
the relevant, trusted and high value CS
metrics of Table 1, and then report them
to CANs distributed within local, regional,
enterprise and global Ops centers. In this
example, there are three administrative
domains represented by the three circles:
Help Desk, Operations and Engineering.
End users also publish and subscribe within
the enterprise system. The network edge

In addition to segregating metrics according to EMMRA CS domain, the network
also categorizes the metrics within those
domains so that the individuals responsible
for resolving the CS threat may be identified
(Table 1).7

The CS agents and CANs communicate over
an out-of-band (OOB) network, such as the
wireless mesh network shown in Figure 2;
therefore they do not impact transport

network. The integrity of the OOB data is
maintained using continual asset discovery
to ensure comprehensive agent deployment
throughout the enterprise system.

EMMRA CS Verification
A large-scale simulation that emulated the
EMMRA CS architecture of Figure 1 was
performed in collaboration with Queen
Mary University of London, on the U.K.
national supercomputing service, HECToR.8
Running this simulation over the network
topology shown in Figure 4 verified that the
EMMRA CS inter-domain and inter-plane
information sharing between CANs enables
detection of CS events originating in one
plane or domain anywhere within the enterprise system. For example, the simulation
was run for Voice over Internet Protocol
(VoIP) scenarios in which the enterprise system was subjected to Denial of Service (DoS)
security threats. For these scenarios, DoS
events detected in the Cybersecurity Plane
resulted in a loss of network connectivity.
Those detected in the Control Plane caused
the reconfiguration of physical network
links. Those detected in the Usage Plane
caused degradation of voice service, and
those detected in the Management Plane
initiated bandwidth re-provisioning. Each
of these security events was stored in the
CAN database for later analysis, such as
total cost impact due to the threat and
cost savings based on the EMMRA CS
response. Note that the CAN database is
not format sensitive, and therefore will not
limit the compatibility of appliances and
other security tools with the EMMRA CS
framework. EMMRA CS provides operators
with visibility across traditional boundaries
that enable them to proactively respond to
security events before they compromise the

EMMRA CS Realization
A unique contribution of EMMRA CS is its
ability to leverage new and existing tools
and methodologies for application to cybersecurity. For example, EMMRA CS adapted
a methodology that was previously used to
evaluate Quality of Service (QoS) mechanisms to support VoIP services based on a
voice delay metric, called the R-factor,9 to
create a novel “whole-of-network” visualization capability from which CS agents can
detect and respond to a DoS attack. This
new software tool, called the Real-Time
Monitoring and Response Tool (RTMRT),
supports both manual and automated
observation, interpretation and response
capabilities for real-time applications.
The manual feature is used for addressing unique problem symptoms that have
not previously occurred and for which no
automated response has yet been determined. In this case, the tool would permit
the network operator to manually click on
a real-time contour, representing the metric
category of interest, and then “push down”
into the next level of monitoring for that
metric category.
At this next level, the structure of the
EMMRA CS framework and reference
architecture directs the network operator
to the most likely place in the enterprise
system where the CS event could have
occurred. At this monitoring level, specific
CS metrics names are applied to permit the
operator to quickly distinguish the exact
problem; thereby enabling faster problem
resolution and QoS restoration.
The tool automates the manual process
for problem symptoms with known resolution approaches, thereby permitting faster
response and resolution for time-critical
issues. Now that RTMRT software has been
tested in a simulated environment, the
next step is to deploy this software in an
operational environment. Instances of the
EMRMA CS hardware agents and CANs
have been designed for and deployed on
operational and experimental networks that
transport data over fiber optic connections
at rates of up to 40 gigabits per second.10
Through its unique approach to cybersecurity event monitoring, management and
response, EMMRA CS addresses the key
enterprise systems service provider goal of
protecting their systems and the data they
carry against cyberattacks. EMMRA CS enables operators and analysts to recognize
the onset of cyberattacks in a timely manner
by proactively identifying the threat(s) and
recommending response countermeasures
to thwart them. Based on the distributed
architecture approach, EMMRA CS is scalable and it enables cost avoidance by not
requiring all capabilities to be implemented
within every operations center. It provides a
cybersecurity solution that applies to DoD,
agency and commercial complex enterprise
systems. •

Mission Challenges Spur
Next Generation Missile Radome Materials Innovations
espite their seemingly simple shapes,
radomes are complex components that
have competing design requirements. The
radome forms a part of the aerodynamic
structure of the missile, and must be able
to support the aerodynamic and structural
loads placed upon it. A radome must protect the sensitive guidance and electronic
components from the captive carry or flight
environment (e.g., sand, rain, hail), while
resisting high flight temperatures. A radome
must also provide an environment that the
seeker can operate in, which may include
low levels of moisture or a prescribed
operating pressure. And, of course, it must
be transparent to the radio frequency (RF)
wavelengths of interest to meet the performance objectives of the missile. Finally, a
radome is no different than any other
missile component in that it must be affordable and lightweight — particularly
important for a radome since it is located so
far from the missile’s center of gravity.
A successful radome design must optimize
the balance of competing requirements. For
example, although higher frequencies or
multiband performance would favor thinner radome walls, thicker walls are desired
to enable the missile to endure the higher
speeds and the larger aerodynamic forces
planned for next-generation missiles.
The ideal material for a radome has the
following properties:
• It has a low dielectric constant and loss
tangent, both of which are constant over
the temperature range of interest.
• It is strong enough to sustain structural,
aerodynamic and aerothermal loads, as
well as resist impacts from adverse environmental agents over all speeds and
flight durations.
• It is lightweight and affordable.
• It is impermeable to water and able to
support a pressure differential between
the radome’s interior and exterior.
• It has consistent material properties
from radome to radome and is easily
manufactured.
The two materials that currently meet many,
but not all, of the ideal characteristics described above are Pyroceram® and slip cast
fused silica (SCFS).
Pyroceram (a glass-ceramic material with
cordierite as its main crystalline phase) and
SCFS (a porous material comprising small
grains of silica glass sintered together) are
currently used at Raytheon for high-temperature missile radomes. Pyroceram is strong
and impact resistant, has good thermal
shock resistance, is water impermeable, and
has a reasonably low dielectric constant and
a low loss tangent. SCFS has a low dielectric
constant and a low loss tangent over a very
wide temperature range, as well as excellent
thermal shock resistance and low thermal
conductivity.

New mission profiles for the next generation
hypersonic interceptor missile push the radome requirements into trade spaces where
Pyroceram and SCFS will not meet the system performance. The main disadvantages
of Pyroceram are that the dielectric constant
and loss tangent increase with temperature,
and the changes become great enough at
temperatures above approximately 800°C
that compensation to account for boresight
error is no longer accurate. The thermal
shock resistance of Pyroceram is also limited and would not support the expected
thermal profiles for planned new rocket motors. Thermal shock stress may be mitigated
somewhat by controlling the flight speeds
or flight profile, especially during the initial
launch portion of the flight, but this is not a
desirable alternative.
The main disadvantages of SCFS are the
porous nature of the material and its
mechanical properties. The mechanical

Approximate upper-use temperatures of various materials for missile radomes are shown. As
a missile flies at higher speeds (and lower altitudes), the radome’s high-temperature tolerance
must increase. Few materials can sustain speeds above Mach 5 at sea level.
Mechanical, Materials & Structures
properties of SCFS limit the aerodynamic
forces that can be imparted to the radome,
as well as the radome’s performance when
exposed to environmental agents, particularly
rain. SCFS is not fully dense and can transmit
water vapor readily from the atmosphere
into the interior of the radome. Attempts to
create a “hermetic” SCFS radome have not
been entirely successful.
The drawbacks of Pyroceram and SCFS have
led to research and development activities at
Raytheon, and at several radome suppliers,
with the goal of producing a material that
meets all of the requirements imposed by
a next generation high speed, all weather
missile. Figure 1 shows the expected thermal environment that the radome must
withstand based on the speed and altitude
of a missile. As the speed increases, and
the altitude decreases at a given speed, the
expected temperature that the radome will
be exposed to increases. The high temperatures that next generation missiles must
endure limit the choice of available materials
to ceramics or ceramic matrix composites.
There are several materials being developed
that may offer the potential for an improved
radome. None of these yet meet all the
desired requirements of an ideal radome.
Three of them are based on composite
technologies, and one is a monolithic ceramic material.
Polysiloxane is a polymer resin containing
silicon that converts to silicon dioxide when
exposed to high temperatures in an oxygencontaining environment. It can be used with
quartz fibers to create a composite, and it
can be processed in a number of different
ways, like traditional organic composites. It
has good dielectric properties and reasonable mechanical properties, but unproven
high temperature, rain impact and hermetic
performance.
A second intriguing material is a ceramic
matrix composite (CMC) with an aluminophosphate matrix and alumina fibers. The
matrix phase is a very stable high-temperature amorphous material that bonds well
to the fiber reinforcement. This material has
reasonably good dielectric and mechanical

properties, but with yet unproven rain impact and hermetic performance.
A new oxide-based CMC based on a radome material used in production of the
Advanced Anti-Radiation Guided Missile
uses alumina fibers in an alumina matrix.
This CMC overcomes the traditional challenge of fiber matrix interface issues by
using nearly identical materials for both. It
has reasonably good dielectric properties
and good mechanical properties, but its
cost may be high and its producibility and
hermeticity are currently unproven.
Raytheon is developing a monolithic ceramic
material called reaction bonded silicon
nitride (RBSN) for high-temperature missile
radomes. It is produced by forming fine
grains of silicon in the shape desired, then
carefully converting it to silicon nitride
through an extended heating cycle in a
nitrogen atmosphere. This is accomplished
without causing significant changes in shape
or dimensions. The resulting product is a
strong, fracture-resistant material with
excellent rain impact and thermal shock
resistance. The material is porous, and due
to this porosity has an effective dielectric
constant similar to Pyroceram, which is adjustable by controlling the material's overall
density. Since it is porous, RBSN requires a
coating to provide hermeticity. Raytheon is
developing several different methods to
form the silicon nitride, including isostatic
pressing and injection molding of the silicon
powder.
Since it is likely that no material, by itself, can
satisfy all of the desired radome requirements, the next-generation radome will likely
be a material system composed of several
technologies. Raytheon’s system approach to
developing such a high speed missile radome
is illustrated in Figure 2. The radome will be
based on reaction-bonded silicon nitride, as
it can withstand the high temperatures, adverse environmental agent impacts and
structural requirements. Hermetic coatings
will be applied to limit the water vapor permeation for the expected environmental
conditions over the life of the missile.
The expected temperatures that a highspeed missile radome will experience are
above 1,000°C with flight times of several
minutes. Heating of the entire radome will
occur, which in turn will heat the interior
space within the radome. Therefore, an
insulation or thermal protection system will
be needed in the radome interior to limit
heat flow from the radome to the seeker.
The insulation must be RF transparent and
not produce debris during use, which
would impair the performance of the
seeker assembly.
To accommodate missiles that operate at
multiple frequencies, properly designed tuning features can be incorporated into the
radome structure to control its electrical
characteristics. This will allow any combination of RF frequencies to effectively transmit
through the radome to successfully guide
the missile to its target.
Drawing on more than 50 years of radome
development, design, manufacturing and
fielding experience, Raytheon is developing
radome materials, hermetic coatings, RFtransparent insulations and tuning features
to develop and produce the best and most
affordable radome assemblies that will meet
the needs of our customers for the next
generation of high speed missiles. •

Elemental Zinc Sulfide (eZnS®)
Provides a Clear View for Missile Systems’ Tri-mode Seekers

imaging systems and, with further process

improvements, ensure high quality and
low cost dome solutions for Raytheon’s
advanced missile systems that use tri-mode
seeker technology.
The Legacy
The requirement that missile IR domes used
in advanced seekers be highly transmitting
across a wide range of wavelengths while
also retaining high mechanical durability
is challenging for either of the two commercially available grades of zinc sulfide
(ZnS). Though chemical vapor deposited zinc
sulfide (CVD-ZnS) exhibits good mechanical strength and adequate transmission at
mid and long wavelengths in the infrared
(MWIR and LWIR), transmission at shorter
wavelengths (near infrared [NIR] and visible)
is insufficient for multimode applications.
However, by further processing CVD-ZnS
at high temperatures and pressures, the
crystalline micro-structure is transformed,
leading to a dramatic increase in transparency across the entire spectral range. This
transformed, highly transparent grade of
ZnS is referred to as Multispectral Grade®
ZnS. It was invented at Raytheon in 1992
(U.S. Patent No. 5126081) and is used today
in high-resolution infrared imaging systems.
Unfortunately, this post-CVD treatment
also reduces the material’s strength and
hardness.
A few years later, Raytheon began work on
a third variant of ZnS to reduce the environmental health and safety risks of growing
ZnS from gaseous precursors like hydrogen
sulfide gas. This material was coined
elemental zinc sulfide or eZnS, since it is

synthesized directly from the elemental
constituents zinc and sulfur. This new
material has the strength and hardness
of CVD-ZnS. Surprisingly, however, the
transparency of eZnS is significantly
higher than the previous CVD material,
particularly in the near infrared (NIR). The
transmittance of all three variants of ZnS
is illustrated in Figure 1. Note that the
narrow absorption band evident in this
figure at six micrometers in wavelength
does not affect either the MWIR or LWIR
transmittance in eZnS. While the beneficial properties of this new material were
recognized, eZnS was produced for only
a brief time. However, the need for a
strong, multispectral infrared material
remained, and in fact intensified with the
advent of multimode seekers.

generation and immediate consumption of the hydrogen sulfide precursor distinguish elemental zinc sulfide from traditional CVD-zinc sulfide materials.
Manufacturing
Figure 3. As-deposited eZnS domes. The current reactor configuration can produce multiple
dome blanks simultaneously; future production-capable furnaces increase the quantity tenfold
and significantly decrease cost per dome.
Reviving the Capability
Early in 2009, a Raytheon team of scientists and engineers, including engineers
who were instrumental in the original
process, began the recovery of the eZnS
process that was first demonstrated almost
fifteen years earlier. This team designed
and supervised the installation and process
prove-in of a new eZnS manufacturing facility (Figure 2).
This was done to meet the urgent need
for a durable, multispectral infrared transparent material. The effort was part of
Raytheon’s collaboration with the Aviation
and Missile Research Development and
Engineering Center (AMRDEC), through
the Army Manufacturing Technology
(ManTech) Program Office. The focus of
this ManTech effort was the implementation of advanced manufacturing and
process improvement methods to reduce
the cost of multimode missile seeker components. An added benefit is an increased
defense industry production capability for
a critical infrared optical material. For this
work, the Raytheon/AMRDEC team was
awarded the 2011 Defense Manufacturing
Excellence Award for Large Business by
the National Center for Manufacturing
Sciences.
The new facility began operation in the
spring of 2009, adding yet another chapter
to Raytheon’s record of infrared materials
innovation. Using a 10-factor, reducedmatrix design of experiments, the Raytheon
team was able to increase the eZnS deposition rate while maintaining the high
optical quality of the material, thus driving
down the production cycle time for domes
by over 30 percent. Elemental ZnS missile
domes produced using the new process are
shown in Figure 3.
ZnS dome post-processing improvements
were also identified during detailed valuestream analyses. Cycle-time reduction
opportunities were found in the milling,
grinding and polishing processes, which,
if implemented even as early as low
rate initial production (LRIP), could additionally reduce dome fabrication costs.
Improvements to the anti-reflective coating
process to address durability of the ZnS
domes in the harsh environments of Army
and Air Force theaters are also underway
(Figure 4).

Post-processing includes hot isostatic pressing and grind/polish process improvements
that enable a low-cost dome solution for the
current Small Diameter Bomb (SDBII) and
potentially for the Joint Air-to-Ground
Missile (JAGM).
technology through advanced manufacturing methods and processes. Thus, the
legacy that began over forty years ago with
the deposition of the first infrared missile
dome using the CVD process continues.
The results of this work will provide a capability to produce affordable multimode
windows and domes for the new generation of sensors for missiles, munitions and
surveillance systems. •
