Abstract
Feature extraction is the key step for acoustic target recognition. Because the acoustic signal is non-stationary, the traditional feature extraction methods can not work well. In this paper, "wavelet analysis method" used for feature extraction is introduced, after simulating and analysing, it is proved that this method is suitable for feature extraction of acoustic signal.
