基于小波变换的磁记忆信号去噪方法研究

Research on Denoising Theories of Metal Magnetic Memory Signal Based on Wavelet Transform

在利用小波变换对油库(站)输油管道的磁记忆检测信号进行消噪处理时,主要有三种方法,基于小波变换的非线性方法能够获得较理想的处理效果。本文详细介绍了基于该方法的信号处理原理,并重点介绍了影响消噪效果的三项因素。非线性方法在工程实践中取得了良好的效果。

There are three main theories all based on wavelet transform, as using wavelet transform processes metal magnetic memory signals of oil depot.Among them, the non-linear technique can achieve the best effect. The article describes the processing theory based on the non-linear technique in detail, and in project practice, the means arrives at the satisfactory effect.
