浅海声速剖面对吊放声纳探测距离的影响
Effect of Sound Speed Profiles in Shallow Sea on Detection Range of Dipping Sonar
摘要
Abstract
The detection range of dipping sonar is related to not only the equipment performance, but also the environment characteristics and the depth of dipping sonar in the water. In this study, acoustic propagation characteristic of different sound speed profiles in the shallow sea was first set forth, and several kinds of typical sound speed profiles were analyzed by simulating ray trace. Then by modeling and calculating the sonar, underwater acoustic environment and target, the active detection range of dipping sonar of different sound speed profiles is simulated by ray model. At last, the effect of the depth in the water of active dipping sonar on the detection range was analyzed. The result shows that the detection range is different if the depth in the water of active dipping sonar is different in the different sound speed profiles, and the performance of sonar can be well exerted and the targets of different depth can be best detected when finding the optimum detection depth of different sound speed profiles.关键词
