The generalized S transform is a relatively new time-frequency analysis method for non-stationary signal, which has the following characteristics and advantages: S transform inverse transform and Fourier transform is directly linked to ensure that it is the non-destructive transform; linear transform ensure there is no cross-terms; time-frequency resolution and the signal frequency-related; basic wavelet do not have to meet the permit conditions; scale makes the generalized S transform have good aggregation ability for frequency. Based on these characteristics and advantages, the generalized S transform has been widely used in seismic exploration. Such as dispersion analysis of Rayleigh surface wave, wave field separation and noising, Extraction of sedimentary cycles and the first-arrive detection of seismic wave, etc. In this paper, we summarize the present representative of the generalized S transform type, and combine with examples, expound the research progress of this method in seismic exploration. Finally, we give a prospect of generalized S transform in seismic exploration.
