摘　　要：吊放声纳是反潜直升机的主要搜潜设备,使用频率高,具有主/被动工作模式、可变深搜索、重复使用等特点。由于海洋环境的影响,当吊放声纳水下分机所处深度不同时,对某一深度的目标最大作用距离存在差别。论文从声传播轨迹和能量传播两个方面分析吊放声纳在不同声速剖面类型下其工作深度对作用距离的影响,对不同水文条件下的吊放声纳工作深度给出合理化建议,对吊放声纳装备性能使用进行优化,提高搜潜效能。Dipping sonar is the main submarine searching equipment for anti-submarine helicopters. It has high frequency ofuse,and has features of active/passive work mode,variable depth search,and repeated use. Due to the influence of the marine environment,when the depth of the underwater sonar submarine extension is different,there is a difference in the maximum effect distance for a certain depth of target. This paper analyzes the influence of the working depth of the dipping sonar on the working distance under different types of sound velocity profile from two aspects of sound propagation trajectory and energy propagation,andgives reasonable suggestions for the working depth of the sonar suspension under different hydrological conditions. The use of dipping sonar equipment performance is optimized to improve search performance.
