目标信号消噪处理是确保引信可靠动作的重要手段。为提高鱼雷磁引信动作的可靠性，基于小波包变换（WPT ）在信号消噪处理方面所具有的良好特性，采用小波包变换对复杂背景干扰下的鱼雷磁引信目标信号进行了消噪处理，并利用 Matlab 软件对消噪结果进行了仿真分析。仿真结果表明，基于 WPT 的消噪方法能够有效地实现对鱼雷磁引信目标信号的噪声抑制，具有消噪效果好，精度高，失真小的特点，有利于提高鱼雷磁引信动作的可靠性。

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 ,wavelet packet transform is used to denoise the mag‐netic fuze signal under a complex background interference ,and a simulation of the denoising results with Matlab is per‐formed .Simulation result shows that the WPT denoising method can effectively eliminate background noise existed in torpe‐do magnetic fuze target signal with higher precision and less distortion ,leading to the improvement of the reliability of torpe‐do magnetic fuze operation .
