Abstract :
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.
