柱形水声换能器作为各类海洋水声设备的关键部件得到广泛应用。对于垂直指向性开角一定的柱形水声换能器，当在浅水和接近海底条件下使用时，海面和海底的界面混响将对其信号接收检测产生严重干扰，是决定其工作深度范围的主要因素。文从界面混响理论入手，对柱形水声换能器在浅水和接近海底条件下界面混响进行理论分析和仿真计算，定量分析对工作深度范围的影响。
柱形水聲換能器作為各類海洋水聲設備的關鍵部件得到廣汎應用。對于垂直指嚮性開角一定的柱形水聲換能器，噹在淺水和接近海底條件下使用時，海麵和海底的界麵混響將對其信號接收檢測產生嚴重榦擾，是決定其工作深度範圍的主要因素。文從界麵混響理論入手，對柱形水聲換能器在淺水和接近海底條件下界麵混響進行理論分析和倣真計算，定量分析對工作深度範圍的影響。

The cylindrical acoustic transducer is widely used in all kinds of underwater acoustic equipments as key com‐ponents .The working depth range of cylindrical acoustic transducer is determined by the interference of interface reverbera‐tion receiving signal detection when it is used in shallow and near the bottom of the sea to the cylindrical acoustic transducer with a certain vertical open angle .In this paper ,the interface reverberation to cylindrical acoustic transducer is simulated and the influence to the working depth range is quantitatively analyzed .
