频率-波数域速度滤波常常用于叠前地震数据,以压制相干噪声。尽管这一方法常常能得到极好的结果,但有时它也会使信号平滑和畸变,同时压制相干噪声的效果很差。一种慢度自适应f-k滤波法降低了信号的畸变,改进了滤波器的衰减特性。该方法采用
Frequency-wavenumber domain velocity filtering is often used for prestack seismic data to suppress coherent noise. Although this method can often yield excellent results, it can sometimes smoothen and distort the signal and suppress poor coherent noise. A slow adaptive f-k filter reduces signal distortion and improves the filter’s attenuation characteristics. This method is used
