摘　　要：海洋锋会对水声信号的传播产生极大的影响,并能削弱潜艇水声通信和声呐探测效果。只有掌握海洋锋对声信号的具体影响,才能在实际作战中有效规避其带来的不利影响。利用射线模型对深海水声环境进行仿真,给出声源在锋两侧的冷水区和热水区中的声线传播图、传播损失图及多途效应的仿真结果,通过与标准深海环境对比,分析海洋锋对潜艇通信和探测的影响。仿真分析结果表明:海洋锋的存在将削弱潜艇通信和探测的效果,但在锋面所处的深度进行水声通信和探测,可在一定程度上削弱其影响。The ocean front will have a great influence on the propagation of underwater acoustic signal,and can weaken the underwater acoustic communication and sonar detection effect of submarine.Only by knowing the specific influence of ocean front on acoustic signal,can we avoid the adverse effect effectively in actual combat.The deep sea acoustic environment is simulated by using the ray model,and the simulation results of acoustic propagation,propagation loss and multipath effect of the acoustic source in the cold and hot water areas on both sides of the front are given.Through the analysis of the simulation images,it is concluded that the presence of ocean front will weaken the submarine communication and detection effect,but the underwater acoustic communication and detection at the depth of the front can make up for this kind of bad effect to some extent,and obtain a relatively good effect.
