WebTo apply reverse‐time migration to prestack, finite‐offset data from variable‐velocity media, the standard (time zero) imaging condition must be generalized because each point in the image space has a different image time (or times). This generalization is the excitation‐time imaging condition, in which each point is imaged at the one‐way traveltime from the … WebJan 1, 1994 · Migration of Seismic Data January 1994 Authors: Ernesto Bonomi CRS4 Centre for Advanced Studies, Research and Development in Sardinia Abstract and Figures …
