The Application Of Triple Correlation Overlap Sampling Method In Improving The Signal-To-Noise Ratio Of Microseismic Signal

Based on extracting the useful signals by removing noise in the seismic signal processing, triple correlation overlapping sampling method of microseismic signal was proposed. The method removes noise and extracts the useful signal by making use of the property that triple correlation of the noise is zero. The steps of triple correlation operations on the basis of overlapping sampling are described in the article. According to the method, theoretical experiments and real seismic data were carried out to test the efficiency of the proposed method, which show the promised in practical application.
