摘要
为高速、实时的处理水声信号,有效提取信号特征信息。开发了一种基于TigerSHARC201DSP平台的水声信号处理算法。首先介绍了TigerSHARC201芯片,然后分单板和板间两部分分别设计了阵列信号处理的DSP网络拓扑结构。设计了关于时频域波束形成的并行算法,并采用了等间距线列阵仿真信号对算法进行了仿真验证。结果表明,应用基于TigerSHARC201数字信号处理机开发的处理算法能高速、实时的实现对水声信号的处理,并为今后进一步深入研究相对复杂的信号处理算法及实现打下了基础。
In order to process the underwater signal real- time at high speed and distill the character of the signal effectually, a underwater signal processing algorithm based on TigerSHARC201 DSP--computer is exploited. Firstly the hardware of the DSP-- computer is introduced, then the DSP topology for array signal processing is designed from two sides that as one DSP board and between two DSP boards. At last the parallel algorithm about the spectrum beam forming and time beam forming is designed and realized, and equal-space-between line array is used to validate the algorithm. The result shows that the software can process the underwater signal real-time and at high speed by the TigerSHAF^C20I DSP-computer, and upbuild the foundation of lucubrating in the future.
