摘　　要：水声释放器作为水下设备辅助回收工具,水下工作时间和工作可靠性严重制约着水声释放器使用条件和效能发挥。论文利用Pattern时延差编码技术的低功耗、低误码率、抗多途干扰等特性,将其应用于水声释放器遥控指令收发通信系统中。通过Matlab系统仿真研究,证明利用Pattern时延差编码方式通信,水声释放器实现一机多控,提高抗多途干扰能力,降低通信误码率,延长水下工作时间。The underwater acoustic releaser is the auxiliary equipment for retrieve underwater devices .Its working time and ability retricts the usage condition and efficiency of underwater acoustic releaser .Using the features of pattern time delay differential coding ,such as low power consumption ,lovo bit error rate ,it is applied in remote control instruction system of underwater acoustic releaser .The Matlab simulation proves that the usage of pattern time delay differential coding can realize one machine with several controllers of underwater acoustic releaser ,improve anti‐multi‐paty interference ability ,decrease low bit error rate and extend underwater working hour .
