Towed fishery detector in horizontality works passively to detect the location of the shoals of fish through detecting their noises. It can facilitate the detection and reduce the cost as well. It can offset the noise in the signals received by the two vector hydrophones in the tow and reduce the interference from the ship for the efficient range of target detection. It can indicate the azimuth of each target by computing relatively on sound pressure and vector velocity and with the help of non-linear optimizing technology and multi-sources distinguishing by single vector hydrophone.
