摘　　要：水声环境参数是影响声呐性能的重要因素。在浅海波导环境下,声速剖面随季节与海域的不同具有复杂多变的特性,而声速剖面对声呐的作用距离将产生较大的影响。针对典型的浅海声速剖面,利用简正波模型对海洋信道的传递函数进行了分析,并研究了其对声呐作用距离产生的影响。Underwater acoustic environmental parameters are important factors affecting sonar performance. In shallow water waveguide environment, sound speed profile has different complex features with different season and sea areas. And the sound speed profile has great impact to the sonar effect distance. In this paper, the marine channel transfer function is analyzed using normal-mode model to the typical shallow sound speed profile. And the effects of its action on the sonar distance are researched.
