Application of Generalized S Transform for Per-Stack Seismic Data Denoising
Jiao Xu · 2007
Based on generalized S transform,a pre-stack seismic signal was transformed from the time domain to the time-frequency domain.It eliminated noise by using the difference between signal and noise in the time-frequency domain,then made use of generalized S transform to return it to the time domain,and obtained the resultant seismic signal which had less noise.It is indicated by the theoretical models and practice that this method could not only denoise effectly in different times and frequencies,but also keep the available information in the seismic record.At the same time it has the characteristics of good flexibility and great application effects.
