The method of feature extraction of radiated noise based on wavelet transform is proposed. Based on this, the effective frequency distribution range of underwater target is obtained. The frequency range is determined for the design of underwater target signal collector. At the same time, the underwater target signal collector Hardware structure, implementation methods and experimental results.
