In response to the demand for feature extraction in underwater target recognition, this article adopts mixed programming technology to design a software implementation method for underwater target time-frequency feature extraction.The time-frequency feature extraction of underwater target radiation noise is achieved through LOFAR and wavelet analysis.The software interface is written using a mixed programming method of MATLAB and C# to build an underwater target time-frequency feature management platform, which can extract, manage, and save time-frequency features, providing a reliable platform for subsequent intelligent recognition of underwater targets.
