Analysis compares two seismic migration techniques to evaluate conditions for effective processing.
Two processing procedures are analyzed in the paper – postacking migration and prestacking migration. They are compared in the phase space to get correctness conditions for the first scheme. That is estimates are obtained for the downward continuation maximum depths and (f, k)-domain geometries, in which the first, a priori most accurate, scheme may be replaced by the second, more economical
