Abstract

With the localizing character of wavelet transform, acoustic signal from water surface using laser light can be decomposed into the detail part of every scale by multi-resolution analysis. The results of experiment show that wavelet analysis has the great ability of noise rejection and is fit for weak signal detection and feature extraction.
