摘　　要：浮标声纳受到功耗、体积和硬件复杂度等因素的限制,通常将接收数据通过无线信道发送到终端设备进行处理。由于多径传播、衰落特性以及多普勒效应等众多因素的干扰,信号在无线通信传递中会产生误码并影响最终系统性能。针对复杂传输信道环境下的浮标声纳系统,研究了误码率对系统的多目标方位估计性能的影响,并通过计算机仿真给出了误码率允许的门限。Due to the limitations of volume,hardware complexity and power consumption,sonar buoy equipment transmits receives signals through wireless channel to the processing terminal on airplane or ship. The multipath effects,fading characteristics,and Doppler spread of communication channel will cause bit error and finally influence the performance of sonar signal processing. In this paper,is focused the DOA estimation performance of sonar buoy under various bit error rates of communication system. The BER threshold of DOA estimation is obtained via Monte Carlo simulation to guide the design of whole sonar buoy systems.
