Summary Spectral Simulation Algorithm is a feasible methodology of seismic wavelet simulating and elimination. As known that seismic signal is characterized as time-varying, also the wavelet changes by subsurface media. Base on the Generalized S-Transform, a time-frequency domain wavelet is created via spectral simulation algorithm, with high consistence of changing trending obtained from time-frequency distribution of the seismic signal. Utilizing this wavelet, frequency band of seismic can be broadened significantly, also seismic data value could be improved for sure.
