Abstract

One-dimensional binary wavelet packet decomposition technology is applied to extract signal feature aim at the target acoustic echo signal in water of active sonar in this paper. The signal feature extraction method and the calculation of order list about decomposition node with frequency band are studied, which are verified and analyzed by different simulation experiment. All of studies designed to support a new technique and thought for the feature extraction of the target acoustic echo signal in water, which based on signal processing.
