Sensing & Surveillance: Expanding

Seabed Awareness

Subsea defense is shifting from inter- mittent seabed surveys to continuous surveillance, driving innovation in so- nar and underwater imaging systems.

Canadian ? rm Kraken Robotics has emerged as a global leader in synthetic aperture sonar (SAS). Its KATFISH sys- tem, integrated with a Towed Synthetic

Aperture Sonar (TSAS), is already in use with multiple navies for MCM and change detection, providing unmatched resolution and area coverage rates.
