Source Heave Compensation for High Resolution Marine Seismic Profiling

摘要

In this paper several compensation schemes for removal of acoustic source heave affects from the seismic echo signal are described and examined. A new compensation method is proposed, in which heave distortion is continuously corrected, irrespective of towing height. This scheme is based on a nonlinear time base display or time varying sampling rate during acquisition of the seismic signal. The method proposed leads to a simple hardware implementation.
