SEISMIC DATA ACQUISITION AND PROCESSING USING NON-LINEAR DISTORTION IN A GROUNDFORCE SIGNAL

摘要

The present invention discloses, in certain aspects, a system and method for improving vibratory source seismic data in which a filter (C) is produced which converts a recorded seismic groundforce signal (118) (including harmonic distortion therein) into a desired short-duration wavelet which is used as the basis for generating a filter (122) for application to the seismic data (124).
