KATFISH™
KATFISH™ is a high speed, actively stabilized Synthetic Aperture Sonar towfish that operates at speeds up to 10 knots. The high speed capability of KATFISH™ when compared to the slower moving ROVs or unstabilized towed sidescan sonar and AUVs, greatly increases Area Coverage Rates (ACR) therefore reducing operating time and cost.
KATFISH™ provides unprecedented high-resolution ACR of 4 km^/hr with 3.3 cm x 3.0 cm* constant resolution across ranges up to 200 m per side with simultaneous 3D bathymetry. *1.9 cm x 2.1 cm constant resolution possible with post-processing.
KATFISH™ incorporates Kraken’s latest generation Real-Time SAS
processor. RTSAS enables real-time processing of SAS imagery and bathymetry. On-board Automatic Target Detection survey data and contacts can be viewed directly on the ship as it is collected, or remotely from a mothership or shore-based command station.
KATFISH™ can be operated unmanned up to sea state 5 in combination with the ALARS system, which offers an autonomous launch and recovery system (ALARS), and intelligent Tentacle Winch®.
From the very beginning, the engineers at Kraken set out to design a towfish with unparalleled resolution and coverage rates to challenge the industry to rethink how hydrographic, pipeline, and mine countermeasure surveys should be conducted. Providing SAS capability and performance at an affordable cost has truly elevated KATFISH™ into a league of its own.
The KATFISH™ system comprises:
- Actively-controlled intelligent towfish
- 180 cm MINSAS
- SAS gap reducer
- Operator console
- Forward looking sonar
