摘要
在东海海域的沉底小目标探测中,混响严重影响了回波信号对有效目标的探测。基于混响信号的局部平稳性结论,采用分段白化滤波器实现了混响背景下的信号次佳检测。仿真结果和海上实验结果均表明,该方法可以较好的抑制混响。
In the detection of the small target around the continental shelf of East China Sea, the reverberation greatly influences echo signal for effective target detection. Based on reverberation signal local stabilization, the paper uses segmented whitening filter to implement signal second best detection under the reverberation background. The results of the simulation and the test in the sea show that the method can restrain reverberation better.
