摘　　要：中尺度涡的存在会影响水声传播。相对于无中尺度结构而言,如果不清楚中尺度涡的影响规律,将极大削弱水下通信和探测的性能,对水下目标如潜艇的安全造成极大的威胁。基于此,利用射线模型仿真深海水声环境,给出存在冷水涡和热水涡时的传播损耗和声线传播图以及多径效应的仿真结果,并与不存在中尺度涡的结果进行对比,分析中尺度涡对潜艇通信与探测的影响。经过仿真对比并结合理论分析得出结论,中尺度涡可对潜艇通信和探测造成较大的影响。其中,热水涡对潜艇通信不利但有利于躲避敌方主动声呐探测,冷水涡对潜艇通信有利但不利于我方探测敌潜艇。The existence of mesoscale vortices will affect underwater acoustic propagation.Compared with the absence of mesoscale structures,if the influence law of mesoscale vortices is not clear,the performance of underwater communication and detection will be greatly weakened,and the safety of underwater targets such as submarines will be greatly threatened.In this paper,the ray model is used to simulate the deep-sea underwater acoustic environment,and the propagation loss and acoustic line propagation diagram in the presence of cold and hot water vortexes are given,as well as the simulation results of multipath effect.Compared with the results without mesoscale vortexes,the influence of mesoscale vortexes on submarine communication and detection is analyzed.Through simulation comparison and theoretical analysis,it is concluded that mesoscale vortexes have a great influence on submarine communication and detection.Hot water vortex is bad for submarine communication but beneficial for avoiding enemy active sonar detection,cold water vortex is good for submarine communication but not conducive to our detection of enemy submarine.
