Katfish synthetic aperture sonar completes first sea trials

14 March 2017

Canadian marine technology company Kraken Sonar has completed Phase 1 sea trials of its new Katfish towed Synthetic Aperture Sonar (SAS) system.

Follow-on Phase 2 testing will complete development and qualification prior to delivery to the launch customer before the end of April 2017. The system is being procured for an unmanned surface vessel (USV) application.

Katfish is an actively controlled, intelligent towfish used to generate real-time, ultra-high resolution seabed images and 3-D maps for a variety of military and commercial applications. The system's primary sensors are based on Kraken's AquaPix Miniature Interferometric SAS (MINSAS) 180 technology.

Although conventional side-scan sonar systems are limited in that they only provide high-resolution images at short range, the use of interferometric SAS technology is claimed to enable Katfish to produce ultra-high resolution (3x3.3 cm) seabed images to very long ranges.
