By exploiting the high Doppler rate of torpedoes, low-latency, high-reliability, and high-mobility torpedo detection, classification and localization (DLC) can be accomplished with joint active-passive sonar signal processing using the hull array. Our system combines passive cues and a new active signal processing technology for deployed waveforms. The signal processing is carried out in real time within a common time-frequency representation for active-passive torpedo DLC but uses a novel technique, invented by, called Doppler-filtered pulse compression (DFPC). DFPC provides high probabilities of detection and correct classification while virtually eliminating confusable clutter. DFPC also provides the high Doppler and range resolution needed to spatially resolve salvos more efficiently than traditional high-resolution waveforms. To make reliable performance predictions for torpedo DLC, a method for extracting, validating, and generalizing highly realistic channel and target impulse response functions from legacy data is proposed.
