Abstract

To analyze underwater explosion signal effectively, the Welch spectrum method had been used to extract the signal features, and by the Mallat algorithm, the whole underwater explosion signal have been gradually extracted by means of one dimensional discrete wavelet transformation. The smooth and detailed parts of the signal had been separated so that the whole signal's features could be more reasonably, precisely extracted.
