The Applications and Prospects of Generalized S Transformation in Seismic Data Processing

We analyze in depth the disadvantages of S transformation (ST). Firstly, the current types,principles and characteristics of GST are combined and summarized. Secondly,the present study results of GST are summarized and analyzed in seismic data processing, including time-frequency domain filtering and de-noising,time-frequency spectral decomposition,primary wave recognition,surface wave suppression,etc.Finally, we analyze and examine the potential applications of GST, which can be used to detect and extract weak seismic signals, filter the seismic data using the method of time variation,analyze the dispersion characteristics of surface wave and image with background noise,etc.
