数字式声纳的实时信号处理

Real-Time Signal Process of Digital Sonar System

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。处理过程不仅计算任务繁重 ,I/O数据率高 ,而且数据流分支较多 ,给设计带来了一定困难。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 process is an important part of sonar system. This part searches and measures targets by processing sound signal. The difficulties of this task include heavy calculating, high I/O data rate and many branches of data flow. This paper introduces the implementation of real time signal process of digital sonar system based on DSP processors array, and the pipelining is discussed.
