基于小波变换的自适应面波压制方法

Adaptive Groundroll Attenuation Based on the Wavelet Transform

采用基于小波变换的弹性模拟自适应面波衰减技术,对地震资料中的面波进行去除。该方法的特点是通过弹性建模的方法预测噪声并进行去除,在去除低频面波噪声的同时,可较好地保留有效信号的低频成分,保证有效信号的连续性和分辨率。

An adaptive groundroll attenuation technology using the elastic modeling based on the wavelet transform is used. The key point of this method is forecasting and removing the groundrolls by elastic modeling. This method can keep effective signals in low frequency components better, therefore ensures the continuity and resolution of effective signals.
