ALTAS at 13 sec
Advanced Light Towed Array Sonar (ALTAS) on Naval Platforms.
ALTAS system consists of mainly four subsystems i.e. Wet end system, Launch/Recovery unit (LRU), On-board
Electronics and System Software.
The Wet End System consists of Transmitter and Receiver Arrays and Tow Cable assembly. The Transmitter Array is housed in a Vertically stabilised body and is hooked on to the seamless Tow Cable with linear receiver Array. The Launch/Recovery unit consists of a Heavy Duty Winch for Deployment, Retrieval and Stowage of tow cable assembly and Receiver Array and a hydraulically operated robotic handling gears for the launch/recovery of the Vertically stabilised body. The receiver array is linked to the on-board electronics through fibre optic telemetry. The on-board electronics consists of transmit waveform generators including power amplifiers for generating the acoustic pulse and specific hardware modules for signal processing and display. The system software which resides on the on-board hardware modules implements advanced signal processing algorithms for target detection and localisation and presents the results in innovative display formats.
