This article is based on the research result of Mallat [1,2] : The local maxima of a wavelet transform detect the location of irregular structures and provide numerical procedures to compute their Lipschitz exponents. We apply this theory into the processing of sound echo for detecting underground. Finally, we get a good outcome.
