Application Research of Audio Signal in Underwater Target Feature Extraction

In response to the application requirements of feature extraction for underwater targets, this article conducts research on acoustic feature extraction methods for WAV audio signals, in order to analyze and process the radiated noise of underwater targets and active sonar echo signals. The article also utilized C#. NET and MATLAB mixed programming technology to develop a software for extracting underwater target features, achieving feature extraction and display of underwater target radiated noise and active sonar echo signals, which has good engineering application value.
