水声对抗仿真系统中的被动声纳仿真

Simulation for Passive Sonar in Underwater Acoustic Warfare Simulation system

针对水声对抗训练是提高海军战斗能力的重要手段。水声对抗中各种设备功能的实现都是声纳的探测基础。传统的声纳仿真研究侧重于信号、信道的仿真,对计算机硬件要求非常高,而且在分布式仿真中需要进行大量的数据交互,会严重影响系统的实时性。为改变现状,采用被动声纳方程为基础,总结出被动声纳方程各项参数的计算方法,得出一种在战术层次对被动声纳建模仿真的方法,在减小网络负载的前提下,合理地反映出各种环境参数对声纳探测范围的影响,方法可以应用于海军舰潜机间战术演练的水声对抗系统中。

Underwater acoustic warfare training based on underwater acoustic warfare simulation system is an important instrument to improve navy＇ s battle effectiveness.Achieving function of the equipments in underwater acoustic warfare is base on the detect of Sonar.In underwater acoustic warfare tactics training system based on distributed simulation,the most important point is the real time feature.Traditional simulation research for sonar emphasizes particularly on the simulation for signal and channel,and the request of computer hardware is on a high level.In the simulation there is a lot of data to interaction,which may seriously affect the feature of real - time.In this paper, based on passive sonar equation,the calculation method of the parameters of the equation is summarized,and a method for passive sonar modeling and simulation on tactics arrangement is given.Under the precondition of reduce network load,it can rationally reflect the effect of sonar＇s detect range caused by environment parameter.The method can be used in underwater acoustic warfare system for tactics training among warship,submarine and plane.
