S-Transform and Its Application in the Spectrum Analysis of Seismic Signal

Abstract

Abstract. S transform combines the characteristic of short Fourier transform and wavelet transform, but the windows used in S transform is invariable, so and it maybe unsuited to some non-stationary procedure such as seismic signal. Thus, generalized S transform is put forward. The effect of S transform and other spectrum analysis methods are compared and generalized S transform is used to predict thin bed. Simulation and processing results of seismic signal demonstrated that generalized S transform can predict the seismic thin bed effectively.
