中文摘要：

thermocline 的存在改变声学的结构并且完成纸分析的健全 rays.This 的方向活跃声纳的工作过程，和在 thermocline 下面的活跃声纳的数学 models.The 察觉概率是 studied.First ，没有 thermocline 的察觉距离被估计，然后， thermocline 检测海底的概率上的深度和健全速度变化的效果被讨论，并且基于一这，寻找 su 上的海条件的效果结果显示在 thermocline 下面，活跃声纳的距离突然变得明显，并且与海调节变得不平，效果是更多清楚。

英文摘要：

The existence of thermocline changes the acoustic structure and effects the direction of the stared rays. This paper analyzes the working processs of the active sorer, and the mathematical models. The detection probaility of the active sonar under thenmoline is studied. First, the detection distance without thermocline is estimat- ed, then the effect of thermocline＇s depth and sound velocity changes on detecting submarine probability are discussed, and based on this, the effects of the sea condition on searching submarine probability is discussed, lastly the distance of active sonar is calculatod under thermocline. The results indicate that tufter thennocline, the distance of the active sonar becomes obvious short, and with the sea condition becoming rough, the effect is more dear.
