An Applied Study on WPT in Denoising Torpedo Magnetic Fuze Signal

Torpedo fuze signal denoising is an important action to ensure reliable operation of fuze. Based on the good characteristics of wavelet packet transform (WPT) in signal denoising, the paper used wavelet packet transform to denoise the magnetic fuze signal under a complex background interference, and a simulation of the denoising results with Mat lab is performed. Simulation result shows that the WPT denoising method can effectively eliminate background noise existed in torpedo magnetic fuze target signal with higher precision and less distortion, leading to advance the reliability of torpedo magnetic fuze operation.
