Abstract

Seismic signal is a kind of nonlinear and non-stationary signal. Using time-frequency analysis to process seismic signal could reserve the primary information maximally and accurately analyze the characteristics of the data in time-frequency domain. At present, there are many kinds of time-frequency analysis methods applied to seismic data processing. Based on the comparison of S-transform and generalized S-transform, the window function of generalized S-transform was analyzed in detail. The result showed that the controlled variable of window function could be simplified. The computational solution of the actual data proved that the effects of the simplified transform are equal to the generalized S-transform.
