Abstract Seismic wavelet is changed in the wake of stratigraphic depth access.The improved S transform in combination with spectral modeling method can overcome time-varying seismic wavelet and avoid the complex window dimension problem.Spectral modeling in the time-frequency domain can well adapt itself to the assumption condition in that the seismic data are smooth and serve as steady signals.Spectral modeling is processed in time-frequency domain,which can overcome time-varying wavelet and improve seismic resolution.A comparison of the effects of the seismic data processing shows that the method can effectively broaden the frequency band and improve seismic resolution.
