SEISMIC SIGNAL DENOISING ALGORITHM BASED ON HHT AND ITS APPLICATION
一种去除地震背景噪音的新方法

On the basis of the Hilbert-Huang Transform(HHT) method and according to the assumption of the background noise signal continuity in time domain,an adaptive algorithm of seismic signal denoising is presented.The algorithm,as used to analyze the seismic wave,has certain positive results.Through the analysis following conclusions can be drawn.1)According to the background noise signal characteristics,the algorithm can effectively remove the low-frequency noise signal from the original signal.2)By the use of t...
