海洋声场预报及战术应用

随着科学技术的飞速发展，对海洋声场做出合乎要求的快速精确预报显得尤为重要。射线模型、抛物线模型、简正波等模型适合于不同具体的海洋声场环境，这些传播模型可以实现声场数值预报的实时性。基于上述模型建立的海洋声场预报系统及对其战术应用进行的研究，对声呐的设计、使用及舰艇作战有着重要的意义。本文在上述模型基础上利用Matlab和Fortran Powerstation工具建立了海洋声场预报系统，使用声场预报系统对典型的海洋环境，即海洋锋、涡漩的声场能量传播规律进行了研究，并提出了在反潜作战中对海洋锋、涡漩、深海会聚区和影区等海洋环境的战术应用。

Ocean acoustic field prediction and tactical application

Today, with the fast development of technology, it is important to predict the acoustic field fast and correctly. Ray models, parabolic equation models, normal mode model etc are adapt to different of concretely matter and can realize real time calculation. These models can realize the ocean acoustic field prediction in spots, on the basis of these models, equipment for prediction and tactical application, there are significance for devising or using of sonar and combating of naval ships. On the basis of these models, this paper establish the ocean acoustic field prediction system by Matlab and Fortran Power,station. Numerical transmission losses in ocean front, vortex are calculated by the prediction system. The paper offer the tactical application of ocean front, vortex and deep ocean convergence zone in the antisubmarine campaign.
