Abstract:
A method for correcting seismic data for distortion caused by the motion of a seismic source and the motion of a seismic receiver, comprising:(a) correcting the seismic data for motion of the receiver;(b) correlating the receiver corrected seismic data from step (a) with a reference frequency sweep signal used by said seismic source to generate seismic waves;(c) computing a forward F-K transform of the correlated data from step (b) to produce F-K transformed data;(d) selecting a constant dip slice of said F-K transformed data;(e) computing an inverse F-K transform of said constant dip slice of said F-K transformed data to produce inverse F-K transformed data; and(f) computing an appropriate correction filter for said inverse F-K transformed data.
