TOMORROW'S SONAR.

Ultra-High Resolution Interferometic Synthetic Aperture Sonar
Introduction to Synthetic Aperture Sonar
Until recently, sidescan sonars and multibeam echo-sounders have been the leading technology for detailed mapping
and imaging of the seabed. However, a new technology called Synthetic Aperture Sonar (SAS) provides ultra-high image
resolution combined with very efficient area survey coverage.
SAS was initially developed for demanding military applications such as naval mine detection and classification. As SAS
technology becomes more affordable, it will find increasing use in civilian markets and become a valuable supplement
to, and in some cases, a replacement for existing sonar technology.

Interferometric Synthetic Aperture Sonar (InSAS) overcomes the resolution, range and operational limitations of
conventional sonar technology. InSAS offers the best of both worlds by synchronizing high resolution seabed imagery
with precise 3D bathymetry. Two vertically separated sonar receiver arrays enable production of detailed bathymetric
maps co-registered with the SAS imagery. This allows bathymetric measurement out to full range, and thus significantly
faster mapping operations.
Kraken’s AquaPix® delivers picture-perfect seabed images with unprecedented image resolution and detail. The system
leverages the sophisticated signal processing capabilities and unique imaging technologies contained in Kraken's
revolutionary INSIGHT™ software for SAS image processing. The software quickly and consistently delivers images with
exceptional resolution and detail that improve accuracy and increase confidence in decision-making. Precision sonar
imaging techniques sharpen detail and enhance the shadow definition of underwater objects. This helps separate
crucial information from clutter and noise for a more accurate representation of seabed imagery.
AquaPix® utilizes military-proven SAS algorithms and robust sonar design to provide an unparalleled level of image
uniformity and detail. It’s a complete system solution that provides cost-effective and ultra-high resolution imagery ideal
for naval mine countermeasures, hydrographic survey, subsea surveillance of strategic assets, habitat mapping, cable
and pipeline route survey and a wide variety of other seabed imaging applications.
In 1969, twenty Volvo bodies intended for the Volvo
manufacturing plant in Halifax incurred severe water
damage in transit across the Atlantic Ocean. With
permission, the vehicles were dumped into the Bedford
Basin, where they sit today in 65 metres water depth. This
image was produced by the AquaPix® during sea trials with
Defence Research Development Canada in August, 2012.
