TOWED SYNTHETIC APERTURE SONAR

High resolution towed Side Scan Sonar for detection and classification of bottom and short tethered mines.

  • Very high coverage rate
    The combination of high speed of advance and long detection range in SAS mode enables rapid large area surveys for military or civilian purposes.
  • High resolution enabling Artificial Intelligence
    The very high resolution of 5cm x 3.5cm up to 150m range is associated with Thales Integrated Automatic Detection/Classification and Target Recognition (ATR) technology to make real-time decisions and to achieve assigned Mine Warfare mission with a high level of confidence.
    It is the key enabler of Thales intelligent mission systems embedded in Autonomous Underwater Vehicles (AUV).

 

PEDIGREE

The T-SAS is the upgraded version of the TSM 2054 SSS (Side Scan Sonar) which has been in service for more than 12 years with the Danish Navy (8 ship sets, 12 vehicles and sonar).

3 ship sets of the T-SAS have been sold to the French Navy under the name of DUBM-44.

T-SAS has been recently ordered by a prominent Navy for an effective survey of major critical traffic lanes. 

OPERATIONAL HIGHLIGHTS

T-SAS includes proven cutting edge Synthetic Aperture Sonar technology for very high resolution as well as high coverage rate.

Picture quality combined with long range and high speed gives the operator a great advantage for rapid sea bottom survey and appropriate decisions.

MAIN CHARACTERISTICS
