摘　　要：本文介绍一种用于声源距离和深度定位研究的２５基元垂直阵的设计、结构及其性能。垂直阵全长１２０ｍ，分为三段。工作段长４０ｍ，由２５个弯曲圆片基元组成。基元在１０Ｈｚ至３ｋＨｚ范围内，接收电压灵敏度为—１９２ｄＢ（参考级１Ｖ／μＰａ），起伏≤±１．５ｄＢ；各路基元相位差在５°以内；加速度灵敏度—６０ｄＢ（参考级１Ｖ／ｇ）。该阵已于９２年８月在海上投入使用，取得十分满意的结果。In this paper a vertical array for localizing the range and depth of the sound source in shallow water is presented. The array consists of three segments,and its total length is 120 m.The work-segment consisting of 25 fluxed circular plates is 40 m in length. The sensitivity of the elements is -192± 1.5 dB (re 1 V / μPa) in the frequency range from to Hz to 2.5 kHz, and the phase difference is less than 5°.The acceleration sensitivity is -60dB (re 1 V / g). An experiment was carried out in the Yellow Sea in August of1992. The result is quite satisfactory.
