摘要
This paper introduces the independent component analysis (ICA) in seismic data processing to enhance seismic data SNR.The theoretical model of ICA to realize the reduction of the seismic data pre-stack noise is established.It firstly extracts the seismic data through designing softwares,and then,uses the S-ICA method to eliminate the noise. After emulating the data of the artificial stack regular interference noise and the actual measurement seismic data,the result shows that the S-ICA has some extent feasibility in practice.
