主动全向声纳浮标性能预测

主动声纳浮标适合探测安静型潜艇,预测主动声纳浮标的性能已成为航空反潜战的重要内容。文章首先简要分析了水声传播模型、海底和海面损失模型以及混响模型等声纳模型的优劣并进行合理选择；在此基础上,提出了一种主动全向声纳浮标性能预测系统的总体方案,并设计了相应软件；最后,针对不同的海洋环境进行仿真实验。该系统能预测主动声纳浮标在各传播方向、水平距离和深度的传播损失及检测概率,可以用于分析浮标性能的时空变化特性,为优化使用声纳浮标提供参考。

Active Omni-Directional Sonobuoys Performance Prediction

Active omni-directional sonobuoys are fit for tracking quiet submarine. The active sonobuoys performance pre.diction has been an important part in aviation anti-submarine warfare. Firstly, sonar models including acoustic transmis.sion model, sea surface/bottom loss model and reverberation model were analyzed and selected. On these bases, the designscheme of a simulation system for active omni-directional sonobuoys performance prediction is presented and the softwarewas established. Finally, simulations under different condition were given. The system can predict transmission loss anddetection probability at any horizontal direction, distance and depth, which can be used to analyze active sonobuoys perfor.mance under different time and space so as to use sonobuoys reasonably.
