一种潜艇规避近距离吊放声纳搜索的方法

潜艇在近距离发现吊放声纳信号后，根据声纳频率和当时水声环境，估测出吊放声纳作用距离，判断其搜索带，在直升机转移探测点时，向吊放声纳已搜索过的区域机动。对该方法进行了仿真分析，研究结果可对潜艇规避吊放声纳搜索提供参考。

A Method of Submarine Evading The Searching of Nearby Dipping Sonar

After the submarine detected the signal of dipping sonar nearby,according to the sonar frequency and the acoustic environment at that time,the submarine estimates the operating range of dipping sonar and judges its search belt,when the helicopter transfers the detecting points,the submarine moves to the area that the dipping sonar has searched.This paper simulates and analyzes the above method,the study result can provide some reference for the submarine to evade the searching of dipping sonar.
