Abstract
Notice of Retraction
After careful and considered review of the content of this paper by a duly constituted expert committee, this paper has been found to be in violation of IEEE´s Publication Principles.
We hereby retract the content of this paper. Reasonable effort should be made to remove all past references to this paper.
The presenting author of this paper has the option to appeal this decision by contacting TPII@ieee.org.
The spatial resolving power for seismic trace before migration is usually estimated by the size or the extent of the first Fresnel zone. Based on the ray path theory, the first Fresnel zone only resolves the kinematics problems of wave propagation. So it´s unable to demonstrate those dynamics characteristic of wave propagation, especially in the complicated seismic wavefield. To obtain a better understanding of the concept of the spatial resolving power for unmigrated seismic data, we had better investigate the spatial resolving power for seismic trace using the theory of generalized diffraction. In this study, we derive the spatial resolving power formula for zero-offset seismic trace with the total response of generalized diffraction stack. And then we demonstrate how to estimate the spatial resolving power for zero-offset trace with the formula. The numerical modeling results confirm the validity of this formula and show that it can deal with the kinematics and dynamics problems of wave propagation in seismic wavefield.
