DESCRIPTION

Decoy, is an acoustic Counter-measure system used by Naval ships. The primary role of decoy is to distract any attacking active and passive homing torpedoes away from the ship and attract them towards remotely generated decoying signals. The decoying signal is electronically generated in the SAC(Signal Analyzer Card). Operating as a self-propelled decoy, it can be launched instantly, at any depth and provide the submarine with an omni-directional protection against attacks by all known torpedoes.

On receipt of a torpedo alert, decoy is launched from the Submarine or external launchers. The system is automatically activated after launch, propelling itself autonomously to its operating position. Torpedo transmissions are received and analysed. After identifying the specific torpedo by its characteristic signature, decoy will select the appropriate deception signals. If an unknown torpedo is encountered, decoy will employ an appropriate deception technique from its portfolio, including Doppler, elongation and range gates, as well as highlights discrimination. Consequently, torpedoes will always prefer decoy as a legitimate target, attacking repeatedly while the submarine performs evasive maneuvers. Decoy can operate for 10-15 minutes at a depth of 300 meters, and will self destruct and sink on the completion of its mission.

Decoy can be accommodated on all types of submarines and has no special installation requirements. It is designed from the submariner's view - as a compact cylinder, it requires only small volume of the valuable submarine space and has been designed to consume no maintenance or facilities on board. No pre-launch tests or presets are required prior to launch, eliminating any chance of human error and ensuring error-proof launch and in-water operation.
