摘要
In the light of the character of the coherence interference in the seismic record and by using the frequency decomposing technology of the wavelet transform,the authors use the radial trace median filtering to separate the coherence interference from the common frequency band of the coherence interferences and signals.The coherence interference is reconstructed by reverse wavelet transform and deducted from original data,and consequently high-fidelity denoise is achieved.Real data processing demonstrates that this method can effectively improve quality of the seismic record and enhance the signal-to-noise ratio of the seismic data.
