The PRE790 system is a com bination of som e m ain com p onents. We can d istinct three
m ain p arts: vid eo p rocessing, serial p ort hand ling and p ow er.
The vid eo p rocessing p art is d ed icated to the UVR m od u le [see 2.2.4.1 M597 – UVR
for PRE790]. The schem atic of this m od u le is d isp layed in Figu re 2-17.

Technical manual
H ardw are overview
Figure 2-17 M 597 schematic overview
The clock sou rces for the system are generated by the USB p rocessor (CY7C68013A),
fu rther called FX2. The Fx2 itself is clocked by a 24MH z TCXO (50p p m , 2p p m / year,
2p p m 0°C -> 50°C). The DSP starts from this 24MH z to generate its core clock of
384MH z by u sing a PLL. The DSP ou tp u ts a 128MH z clock that’s u sed by the PLD
and the SDRAM d evices.
The JTAG bu s of the DSP is on a connector for em u lation and in system d ebu gging.
The DSP EEPROM, w hich contains the p rogram , can be rep rogram m ed by the FX2 so
that the DSP firm w are can be u p d ated via the USB connection. The JTAG connections
of the PLD are available on a connector, bu t are also connected to FX2 I/ O lines so
that the PLD can be rep rogram m ed in system via the USB connection. The FX2 can
rep rogram its ow n EEPROM, this resu lts in a com p lete u p d ateable system via the
USB connection.
The I and Q vid eo signals of the rad ar receiver are connected to the Analog_CH 1 and
Analog_CH 2 inp u t. These inp u ts are term inated w ith 50 ; the inp u t range goes from
-2V till +2V. After the inp u t the sign als are low p ass filtered , the 3d B p oint of this
filter is at 11MH z. Figu re 2-18 show s the frequ ency vs. attenu ation grap h.

Figure 2-18 M 597 analog input circuit frequency vs attenuation
The analog signal w ill next be d igitized w ith 12bit resolu tion, 7.5MH z sam p le rate.
This d igital version of the signal is given to the DSP for fu rther p rep rocessing.
The DSP p rep rocessing w ill take fou r consecu tive sam p les and m akes an average; th e
resolu tion is increased to 14bit, the sam p le rate d ecreased to 1.875MH z. The
resu lting vid eo signals are aligned w ith the trigger signal (range zero), are tim estam p ed , ACP and ARP inform ation is ad d ed and then send to the p rocessing
com p u ter over USB w here they w ill be fu rther p rocessed [see 3.1.2 PSR extractor
DLL]
Besid es vid eo p rocessing the UVR w ill also hand le the com m u nication w ith the
PCT791 u nit, GPS450 m od u le and UDR m od u les. Therefore the UVR need s an
extension m od u le M576. A schem atic overview of this m od u le can be seen in Figu re
2-19.

The trigger signal com es from the PCT791 u nit, and is u sed as range zero m ark to
align the vid eo w ith. The rad ar transm itter is fired at the rising ed ge of this signal.
The rad ar clock signal com es from the PCT791 u nit; it is u sed to generate the analog
d igital conversion clock. The frequ ency of this clock is 30MH z, the ADC clock is 30/ 4
= 7.5MH z. ACP and ARP signals are antenna inform ation signals. This inform ation is
ad d ed to the vid eo signals and forw ard ed to the UDR m od u les. The Fx_Tx and
Fx_Rx signals are u sed by the serial p ort com m u nication betw een the tw o FX2
p rocessors (one on the UVR, the other on the PCT791). This serial p ort is u sed to
read / w rite p aram eters and to u p d ate the flash content of the PCT791 u nit. UVR_Tx
and UVR_Rx lines are reserved for a com m u nication betw een the tw o PLD’s in the

3.1.2.1
Technical manual
Software overview
At startu p of the extractor system the DLL op ens a connection to a PRE790 d evice
(called LIVE m od e) or a p reviou sly record ed 2MH z vid eo file (called REPLAY
m od e). For the fu rther d escrip tion it’s called “d evice”.

In case of live m od e the d ata is received over an USB2.0 connection w hich m u st
exclu sively u sed for the PRE790 d evice d u e to band w id th requ irem ents. This m eans
that no other high band w id th d evices m u st be connected to the sam e com p u ter. A
m ou se, keyboard , UDR is not a p roblem .
The DLL receives the interrogation sw eep d ata in the form at fou nd in section 4.1
from the d evice w here it’s fed to a FFT filter bank. It calcu lates a 16 bin FFT resu lt for
the cu rrent cell by u sing the d ata at the sam e range of the p reviou s 15 interrogations,
see Figu re 3-4
Figure 3-4 16-bin FFT calculation mechanism
This m eans that for each cell sixteen resu lts are ou tp u tted . These resu lts are
com p ared against the:
clu tter-m ap valu e for that cell [for m ore inform ation abou t the clu tter-m ap
see section 3.1.2.2 The Clu tter-m ap ].
The CFAR valu e for the cu rrent cell [see section 3.1.2.3 CFAR]
The FFT resu lt w ill be ou tp u tted as a rep ly w hen the cond ition (3-1) is tru e. This
ou tp u t is called the rep ly vid eo stream .
FFT valu e [d B] > clu tter-m ap valu e [d B] + MAX(CFAR;Threshold ) [d B] (3-1)
The inp u t d ata of the d evice is also fed to a record er; this m akes it p ossible to record
the inp u t stream for later p layback (in rep lay m od e).
The sector m essages p art of the DLL generates 32 sector m essages p er rotation, the
m essages are fed to the PPI engine [see 3.1.6 PPI].
The GPS com m u nication block read s inform ation from the GPS if connected . This
inform ation is u sed for tim e-stam p ing.
For m onitoring of the several calcu lation and p rocessing step s there is a p robe ou tp u t
foreseen. It stream s the selected p robe d ata ou t at a p re configu red UDP socket. The
control of this p robe is d one by the p robe stream er engine [see 3.1.7 Probe Stream er].

The Clutter-map
A clu tter-m ap contains static objects seen by a rad ar: for exam p le m ou ntain
reflections, obstacles or other non m oving p arts. On the other hand , also d ynam ic
objects like w eather can be stored in the clu tter m ap , these are slow m oving objects.
This m eans that the clu tter m ap is continu ou sly changing w hile the Extractor is
ru nning.
The clu tter-m ap consists of cells containing the exp ected backgrou nd reflection signal
am p litu d e for that region . For each p rocessing channel there is a clu tter -m ap (sixteen
in total). The size of a clu tter -m ap is 1024 by 1024 cells, d ata is 8 byte = 8Mbyte. The
p hysical size of a cell is 2 range u nits at 4 ACP u nits (see Figu re 3-5) thu s eight
resolu tion cells share the sam e clu tter -m ap cell.

Each scan the clu tter-m ap is ad ap ted to the new FFT calcu lations. This u p d ate
p rocess is d iscu ssed in section 3.1.2.2.3 Clu tter-m ap ad ap tation p rocess.
At startu p the clu tter-m ap is load ed from file, if there’s no clu tter -m ap fou nd on d isk
or it’s ou t of range [see 3.1.2.2.1 Clu tter-m ap com p are p rocess], the system w ill bu ild
a new m ap [see 3.1.2.2.2 Clu tter-m ap bu ild p rocess].
3.1.2.2.1
Clutter-map compare process
At startu p of the extraction p rocess the softw are w ill d eterm ine if the clu tter -m ap
load ed from d isk is still valid for the cu rrent environm ent. This check w ill only be
execu ted on the zero bin clu tter-m ap , assu m ing that if this m ap is ok, the rest w ill be
also ok. The com p are p rocess is m anaged by the Extractor Server engine [see 3.1.1

3.1.2.2.2
Clutter-map build process
When a clu tter-m ap is not fou nd at startu p or the load ed clu tter-m ap is ou t of range,
the system w ill start in cold -start m od e. This m eans that the clu tter -m ap w ill bu ild u p
from scratch. This p rocess is m anaged by the Extractor Server engine [see 3.1.1

At the beginning of the bu ild p rocess, the extractor control w ill configu re the DLL
w ith the follow ing p aram eters: Up Step =50d B; Dow nStep =25d B; Threshold =200. The
clu tter-m ap contained by the DLL m em ory w ill be all set to 0. N ow the clu tter -m ap

the w ork, every scan the bu ild p rocess w ill d ecrease the u p - and d ow nstep w ith a
factor 0.75; this p rocess rep eats 12 tim es. The resu lt is that after 12 scans the clu tterm ap s have ap p roached the FFT resu lt valu es w ithin a certain range. In Figu re 3-6 you

can see an exam p le of the ap p roach of a fixed valu e of 60,52d B in 12 iterations. In real
the goal valu e is not stable; this w ill increase the ap p roxim ation error.

In Figu re 3-7 you can see in the left figu re the ap p roach valu e versu s the goal valu e
for goal valu es going from 0 to 150. In the right figu re you can see the error
(ap p roxim ation – goal valu e).

At the end of the bu ild p rocess the m ap s are increased w ith 6d B to create a save
m argin, next the m ap is saved to d isk and the bu ild p rocess is end ed . The p reviou s
settings of u p step , d ow nstep and threshold are set back as befo re.

Clutter-map adaptation process
Each scan each clu tter-m ap cell is u p d ated accord ing to the resu lts of the FFTcalcu lations for the resolu tion cells belonging to that sp ecific clu tter -m ap cell. This
ad ap tation p rocess is au tonom ou s m anaged by the DLL
There are tw o m ap -p aram eters d efined ; u p step and d ow nstep , w hich are u ser
controllable. If all FFT resu lts of the resolu tion cells are low er than the clu tter -m ap
cell valu e, then the valu e of the cell w ill be d ecreased w ith d ow nstep . If the ou tcom e
of one of the FFT calcu lations for the resolu tion cells is higher then the cu rrent
clu tter-m ap cell valu e, the valu e w ill be increased w ith u p step .

CFAR
CFAR or Constant false alarm rate is u sed to d etect target retu rns against a
backgrou nd of noise, clu tter and interference.
The CFAR threshold level is calcu lated by estim ating the level of noise floor arou nd
the cell u nd er test (CUT). This can be fou nd by taking a block of cells arou nd the CUT
and calcu lating the average p ow er level. To avoid corru p ting this estim ate w ith
p ow er from the CUT itself, cells im m ed iately ad jacent to the CUT are ignored
(referred to as “gu ard cells”). The im p lem entation in the TA10 extractor contains the
GOCA CFAR algorithm , this m eans that the average is calcu lated before and after the
CUT (taken som e gu ard cells into accou nt). Of both averages the m axim u m one is
taken. This obtained valu e is an estim ation of the noise floor for the CUT. This val u e
is m u ltip lied w ith a factor (linear) to obtain a threshold valu e ( See Figu re 3-9 CFAR
algorithm ).

After p assing the first filter the rep ly grou p is analyzed for sp ectru m content. It w ill

Score = [(a x 1000) - g_qf] x s_qf + (m se-g_m se) x s_m se + (length – g_length) x
s_length (3-4)
a = the qu ad ratic p aram eter of the p arabola (ax²+bx+c)

Length = the nu m ber of interrogations in beam
g_qf , g_m se, g_length= these valu es d efines the id eal target beam .
s_qf, s_m se, s_length = these are the w eighting factors of each term in the score su m .
This score is com p ared against a threshold valu e. When the score is below the target
valu e, a target is d eclared , w hen above the target valu e, the d ata is d iscard ed . The
goal is to have a zero score (id eal target).

Combiner
3.2.2.1
Functional Description
The combiner queue is filled by the PSR and SSR plot extractors. The data streams
must be synchronized, i.e. the combiner can operate properly only if the two streams
synchronized within the limits of the processing delay. Two input streams of plot
data are internally time stamped and inserted in the combiner queue. The combiner
extracts the PSR and SSR plots from the queue, produces PSR SSR and CMB plots
within the specified timeout, and put the results in the tracker queue. The plots are
combined when the corresponding PSR and SSR plots are located within the
specified time, range and azimuth windows. The timestamp of the combined plot is
set identical to that of the PSR plot, the positional info (range, azimuth) are computed
as the weighted average (percentage PSR[%]). To monitor the combiner performance
(combining rate [out]) as the average number of the combined plots per second is
used.
3.2.2.2
Design
The task of this engine is to synchronize both inp u t stream s, PSR and SSR p lots, and
to m atch a PSR p lot w ith a SSR p lot (=com bining). If no m atch is fou nd , the original
d ata w ill be m aintained . The ou tp u t d ata stream of this engine is forw ard ed to the
tracker m od u le [see 3.2.3 Tracker], the d ata exist of PSR only, SSR only or com bined
p lots. An overview of this engine can be seen in Figu re 3-21.

Design
The tracker engine grou p s several p lots to a track. The incom ing p lots are stored in a
kind of FIFO bu ffer and w ill stay there for a m axim u m tim e (=tracker d elay). If the
tracker d elay is exp ired for a p lot, the tracker w ill calcu late the best m atching track
for that p lot, if there’s no track fou nd then a new track w ill be initiated .
An overview of the tracker engine can be view ed in Figu re 3-27.

Figure 3-27 Tracker overview
The calcu late p robabilities block w ill calcu late the chance that a p lot belongs to an
existing track. Based on these calcu lations the select best m atches block w ill d ecid e
w hich p lots belong to w hich track. After the calcu lations there is a track u p d ater
block w hich u p d ates the track w ith the cu rrent p lot inform ation. It w ill also calcu late
the exp ected p osition of the follow ing p lot rep ort by u sing ad ap tive Kalm an filters. If
no m atching track w as fou nd there w ill be a new track started if certain cond itions
are satisfied . Tracks that aren’t u p d ated for a p eriod are d rop p ed and an End Of
Track (EOT) m essage w ill be generated . Track info is ou tp u tted to the Track stream er
m od u le [see 3.2.4 Track Stream er].
The load lim iting block m onitors the engine loop tim e, if it’s too high the p lot FIFO
w ill be flu shed and d ata w ill be lost. This p revents an engine stall.
The tw o blocks at the right are both com m u nication blocks. The first,
Tracker/ Com biner Server m anagem ent interface, is u sed to com m u nicate w ith the
tracker server engine by triggering events in the tracker engine. The second , Tracker

Inqu iry: the client asks som e inform ation abou t the system . The inqu iry is forw ard ed

* The tim e of d etection is com p osed ou t of tw o field s. To obtain a tim e of
-32
second s you need to m u ltip ly the Tim eL valu e w ith 2 and ad d it by Tim eH .
ToD [sec] = Tim eH + Tim eL x 2

** sam p le rate of vid eo signal is 1.875MH z, so the size of a range cell is
0,0432N m {(1/ 1.875[MH z] x 150[m / u s]) / 1852[m / N m ]}. Maxim u m range is
1532 x 0,0432 = 66N m

5. Network overview
The netw ork top ology of the PSR extractor system is show n in Figu re 5-1.
Figure 5-1 PSR extractor network topology
The server, also called p rocessing com p u ter, has tw o norm al LAN connect ions.
LAN 1 is u sed to connect to the local netw ork. LAN 2 is site d ep end ed ; it’s u sed to an
external netw ork via an op tional rou ter. The server has also a DRAC netw ork
connection. This connection can be u sed to m anage the server totally rem ote. For
m ore inform ation see the IE-PSR-Extractor-UM-Vxx m anu al. All these netw ork
connections are connected to a sw itch.
The CAM com p u ter has only one LAN connection w hich is connected also to the
sam e sw itch as the one for the server. This connection is u sed to send / receive d ata,
m anage the server etc…
On these LAN connections there are several netw ork sockets u sed . Table 5-1 gives an
overview of these sockets.
