Abstract
A stern torpedo defense system uses a pair of passive sonar towed tacticaletectors in tandem alignment to detect the presence and trajectory of a stern torpedo attack. The detectors are towed below the wake of a surface ship and include arcuate arrays of transducer elements mounted in low self-noise, roll pitch and yaw stabilized platforms. The region aft of the stern of the ship is examined by an overlapping plurality of preformed passive sonar beams of preselected beamwidth. Signal processing means monitor the power level of the beams and detect the presence and trajectory of an attacking torpedo so that suitable ordinance may timely and effectively be deployed to destroy the torpedo and thereby thwart the attack.
