摘要
从双基地声纳方程出发,分析了航空双基地探测条件下,声传播模型、目标特性模型、环境噪声模型以及混响模型的优化选择,提出了航空双基地声纳性能预测方法,并针对典型的海洋环境进行了仿真实验.仿真结果表明该模型和仿真方法能预测不同态势下航空双基地声纳的信号余量和检测概率,可为航空声纳优化使用提供参考.
Based on the bistatic sonar equation,optimal choice of sonar models including acoustic transmission model,bistatic target strength model,environment noise model and bistatic reverberation model are given and analyzed under bistatic detection.The Forecasting scheme applies to airborne bistatic sonar performance is proposed,and related experiment is implemented under typical ocean environment.Simulation result shows the model can predict signal excess and detection probability of sonar under different state,which will provide reference for airborne sonar usage.
