基于小波模极大值的自动机信号降噪方法

Noise Reduction Method Based on Wavelet Modulus Maximum for Automata Signals

自动机的运动信号主要包括位移信号、速度信号等,这些信号中的噪声严重地影响我们分析判断自动机运动的真实过程。运用小波模极大值方法对自动机运动信号降噪,并对处理结果进行了详细的分析。分析结果表明:小波模极大值降噪方法在武器自动机运动信号分析中有比较好的去噪效果。

The automata motion signals （displacement signal, velocity signal, etc. ） are generally accompanied with the noise, which seriously affect us to determine the true motion state. The wavelet modulus maximum is applied to automatic machine motion signal noise reduction in this paper. Analysis results show that the denoising method has good denoising effect in automata motion signal analysis.
