浅海是水声对抗发生的重要区域,因此对其声信道的研究具有重要意义。采用射线声学理论,建立了一个多途浅海声信道仿真模型。在水声对抗仿真系统中,选用基于AdSP21160的HAMMErHEAd PCI予以实现,取得了预期的实时效果;海试验证结果表明,该模型同样适用于实际情况下浅海海域的声传播损失等参数的折算,可作为水声对抗器材性能预报及战术使用的参考。Underwater acoustic warfare will happen mainly in shallow water region.So study on its acoustic channel is an important task.Based on the Ray Acoustics theory,a simulation model of multi-path shallow water acoustic channel was established.Used in underwater acoustic warfare simulation system with ADSP21160-based Hammerhead PCI,the prospected real-time results were achieved.When it was used in shallow sea trial for parameters calculation such as transmission loss,reasonable results were gotten.The facts imply that the proposed model can be used in performance prediction and tactical reference of acoustic countermeasures
