OPERATIONAL HIGHLIGHTS

A simple rugged design for sea operations which allows the ASW units to maximize the detection of extremely quiet submarines.

The system is designed to deploy the array at optimum depth to continuously survey 360 degrees with a well covered water column, thus overcoming harsh propagation conditions and surface-layer problems inherent to Hull Mounted Sonar.

 

MAIN CHARACTERISTICS

System features:

• For platforms > 300T

• Operated either from a single dedicated console or from CMS Multi-Function Consoles.

• One single winch deploying both the transmit Towed Body and the linear receive array.

• Bottom safety warning functions.

• Performance prediction function for Sonar optimisation.

• Comprehensive Built-In Test capability.

• 20 ft ISO containerised solution for ASW mission modules.

• Multi-static capability with most of the current low frequency sonar in operation worldwide.

Transmit array features:

• One Free Flooded Ring Transmit Array.

• 360° bearing omni-directional transmission.

• Low reverberation effect, due to its vertical directivity. Receive Triplet Array Features:

• Instantly resolves right/left ambiguity issue.
