| 摘 要： | 为改善水声探测系统的信号检测性能,研究了在深海环境下水声探测的特性.在对浅海和深海声传播特性进行比较的基础上,分析了深海声传播的优越性.通过对不同海洋深度声源的声传播特性仿真分析,证明了深海环境有利于实现远距离声传播.在一定信号接收带宽的情况下,计算了位于深海区域的水声探测系统对安静型潜艇的最大被动水声探测距离,进一步证明了深海环境有利于实现远程水声探测.研究结果为在深海环境下探测安静型潜艇提供了理论依据.

| Abstract: | For improving detection performance of underwater acoustic detection system,characteristics of underwater acoustic detection in deep sea were studied.Based on comparision of characteristics of acoustic propagation in shallow sea and deep sea,superiority of acoustic propagation in deep sea was analysed.By simulation analysis of acoustic propagation characteristics of sound sources located on different depth,it was testified that deep sea surroundings is advantageous to realize long-distance acoustic propagat... |
