摘　　要：提出了一种基于VME总线的多通道水声阵列信号数据采集系统的设计方案,该方案中多达36个通道的水声阵列信号由一片Datel公司的ADS927来完成。单通道采样率为80KHz,分辨率为14比特。该系统可用于水下实时阵列信号处理。This paper provides a scheme of designing underwater acoustic array signal sampling system based on VME bus. In this scheme, 36 - channels underwater acoustic array signals are sampled by one ADS927 whose precision is 14 - bit. The sampling frequency in each channel is 20KHz. This system can be used in real time underwater acoustic array signal processing system.
