The invention discloses a method for correcting errors of a towed sonar system by using neighbor interference, which belongs to the field of overall integrated design and comprises the following stepsof: after reaching a preset sea area, constructing a transceiving dual-channel by using a fixed sound source on a neighbor naval vessel as an interference emission source and using own towed sonar tobe corrected and hull sonar as receiving ends; simultaneously acquiring a series of target information sequences are through transceiving dual channels, a warship hull sonar and a towing sonar by using pulse signals emitted by a neighbor warship in all directions; performing data arrangement and smoothing processing on the target information sequence to obtain an interference azimuth informationsequence after arrangement and smoothing processing; solving a conversion coordinate parameter according to the geometrical relationship among the warship shell sonar, the warship dragging sonar, theneighbor warship and the conversion projection; and obtaining a towed sonar direction-finding and distance-measuring converted value under the real target by adopting the statistical value of the converted coordinate parameter. System error correction of towed sonar of different water surface platforms can be supported.
