摘要
本文提出一种基于小波变换的多径回波检测的新方法。该方法通过对回波信号的局部奇异性的检测和处理，确定回波数目和定位各个回波到达时刻，计算机模拟的结果证实了本文所提方法的有效性。
A new multipath signal detection based on wavelet transform is described inthis paper. By means of the detection and processing of local singularity in signals,the number of echoes is determinated and the arrival instant of every echo is located.The results of computer simulation show that this method is effective.
