Heave Compensation of Shallow Marine Seismic Reflection Records by Kalman Filtering

The purpose of this paper is to present a procedure for data filtering to compensate for the heave´s effects of the towed body dynamics, in shallow marine seismic reflection records. The Fourier transform of the heave component record provides the basis for a proposed linear model for the heave motion. A formulation of the heave compensation requirement as a Kalman filtering problem in optimal linear estimation theory is presented. A discussion of the computational aspects and practical results are given to conclude this paper.
