Many forms of seismic noise contaminate our seismic recordings, degrading image quality, the wide range of noise generators means that no single noise attenuation technique will work in all situations. Accord to noise characteristic, we adapt targeted processing technique to remove noise. 1) Cross-spread 3D FKxKy filter to remove ground roll and low velocity linear noise. 2) For anomalous noise attenuation, adapt frequency domain 3D spatial median filter.
3) Linear noise, adapt high resolution Radon transform to remove linear noise.
