实时数字信号处理是声纳系统中的重要组成部分，通过对水声信号的分析处理完成对目标的搜寻和测量。介绍了用DSP处理器阵列进行水声信号实时数字处理的实现方案，着重介绍其中的流水线并行处理。
Real-time digital signal processing is an important part of the sonar system, through the analysis of underwater acoustic signals to complete the target search and measurement. This paper introduces the realization scheme of real-time digital processing of underwater acoustic signal by using DSP processor array, and emphatically introduces the pipeline parallel processing.
