MTR MTR 100 100Kraken is a marine technology com- pany engaged in the design and devel- opment of high performance sonars and acoustic sensors for military and commercial applications.It is leading developers of Synthetic Aperture Sonar (SAS), a sonar tech-nology for ultra-high resolution seabed imaging. SAS uses sophisticated signal processing of successive acoustic pings to form an image with much higher resolution than conventional sonars. SAS was initially developed for mili- tary applications such as naval mine detection and classiÞ cation. As SAS technology becomes more affordable, itÕs expected to Þ nd wide use in civil- ian markets and become a valuable supplement to, or even a replacement for, conventional sonar technology. SAS is also emerging as an ideal sen- sor for unmanned underwater vehicle applications. By using vehicle motion to create a long synthetic array, image resolution can be increased by an order of magnitude or more compared to tra-ditional side scan sonars. SAS technol-ogy is also well suited for interferomet-ric processing, facilitating very high resolution imaging and 3D bathymetry imaging from the same sensor. SAS, a fairly new technology, pro- vides ultra-high image resolution com-bined with very efÞ cient area coverage rates. Kraken has successfully devel- oped AquaPix, an advanced, ultra- high resolution Interferometric Syn-thetic Aperture Sonar (InSAS) with 3D bathymetric capabilities. AquaPix is primarily designed for use on AUVs, ROTVs, ROVs and Tow Bodies and is capable of generating practical image resolutions of 3cm across swath widths of 600m. It can also produce bathymet-ric data with a resolution better than 25cm out to full range while delivering very high depth accuracy. In parallel with the hardware design, senior sonar scientists at Kraken have developed a complete software package for InSAS imaging called INSIGHT (INterfero-metric Sas ImagingGeoreferenced High-Þ delity Toolbox). Both AquaPix and INSIGHT were developed by KrakenÕs team of scien- tists and engineers over a record time span of less than 18 months. The Þ rst system was successfully integrated and deployed onboard DRDCÕs Arctic Explorer AUV in Halifax, Nova Sco- tia in August, 2012. All of the InSAS software processing was performed by KrakenÕs INSIGHT toolbox. L-3 Klein, a division of L-3 Marine & Power Systems is a leading sensor technology provider that designs and manufactures high-resolution sonar systems and radar-based security and surveillance systems. L-3 Klein is a sensor technology pro-vider that manufactures and designs high-resolution sonar systems, and radar-based security and surveillance systems. The Klein S5900 is a COTS multi-beam Side Scan Sonar with sen-sors and capabilities that are suited to mine-like object detection. The sonar provides high speed, high resolution imaging with 100% bottom coverage in detection and classiÞ cation modes. The addition of KleinÕs gap Þ ller so- nar on the S5900 tow body, provides single pass coverage in the sonar nadir region, thus enabling very fast cover- age rates that reduce survey times by 40% or more. The high background- to-shadow contrast ratio of the S5900 enhances bottom features and target deÞ nition while active motion com- pensation and advanced beam-forming technologies nullify blurring caused by tow body motion. The Klein UUV-3500 product line leverages a powerful Ð wholly FPGA implemented Ð multi-channel process-ing engine. The UUV 3500 operates exclusively with L-3 KleinÕs propri- etary wideband technology providing unmatched side scan range and reso-lution performance in a low power, compact and lightweight payload. The system electronics will easily inte-grate into all small Unmanned Under- water Vehicles (UUV) platforms cur- rently on the market and is available in a water tight pressure case conÞ gura-tion. L-3 KleinÕs newly designed, rug- gedized transducers can be molded to meet the vehicleÕs space and conÞ gu-ration requirements and are built to last and perform in the most demand-ing environmental conditions L-3 KleinÕs Side Scan Sonar data acquisition and display software, So- narPro, is now available in Chinese as well as English and Japanese languag-es. KleinÕs SonarPro offers operator control, data acquisition, and display of both bathymetry and side scan data was developed for users by users of Klein side scan sonar and bathymetry products.
