Patent ID: 7639565

Claim:
A point source localization sonar system comprising: a towed hydrophone array adapted to be towed behind a ship for receiving acoustic signals in water via a plurality of hydrophones and outputting acoustic array data; a plurality of non-acoustic data sensors incorporated in said towed hydrophone array for measurement of forward and aft depth, heading, and temperature and for outputting non-acoustic array data; a navigational interface on the ship for determining navigation data including heading, depth, speed, latitude, and longitude; a communication link connecting said towed hydrophone array, said non-acoustic data sensors, and said navigational interface; a matched-field processor capable of processing the acoustic array data into frequency-wave number data; and a non-acoustic data processor including a bathymetry database and acoustic environmental model, said non-acoustic data processor capable of processing the non-acoustic array data and navigation data and extracting data from said bathymetry database and said acoustic environmental model to generate replica data.
