Abstract: It is essential to seismic data processing that event is recovered clearly from noisy seismic data without losing energy of the signal. The time-frequency peak filtering (TFPF) based on pseudo Wigner-Ville distribution (WVD) was applied to process common shot point seismic record to eliminate the noise. This method achieved an unbiased estimation of the complex seismic record. The efficient information in seismic data was enhanced, and the random noise in the seismic data was removed, and the seismic event was recovered effectively. Compared the results from practical seismic record before and after TFPF processing, the effective information in seismic data was enhanced evidently, and the continuity of event was improved simultaneously.

Key words: enhancement of signal, time-frequency peak filter, pseudo WVD, common shot point record
