Abstract

THE S TRANSFORM IS A TYPE OF TIME-FREQUENCY TRANSFORM. IT IS BASED ON A MOVING AND SCALABLE LOCALIZING GAUSSIAN WINDOW. IT IS POSSIBLE TO DESIGN A TIME AND FREQUENCY DEPENDED FILTER USING THE S TRANSFORM. IN THIS STUDY WE DESIGNED A WEIGHTED FILTER BASED ON THE S TRANSFORM. ACCORDING TO OUR RESULTS, THE DESIGNED FILTER IS SUITABLE FOR NOISE ATTENUATION FROM NMO CORRECTED GATHERS WITH STATIC SHIFTS UP TO 0.03 S. IN ORDER TO MAKE THE FILTER APPLICABLE TO THE PRE NMO CORRECTED DATA, A GENERALIZED S TRANSFORM WAS USED. THE NOISE REMOVAL RESULTS FROM WEIGHTED FILTER BASED ON THE GENERALIZED S TRANSFORM SURPASSED OUR EXPECTATIONS.
