Calgary Summary We investigate the amplitude behavior of nonzero-offset phase-shift migration in two and three dimensions. By transforming phase-shift migration into an equivalent Kirchhoff migration we find the deviation of the phase-shift migration operator from “true-amplitude.” We also investigate the amplitude error introduced by anti-aliasing for both phase-shift and Kirchhoff migration. Even for fairly routine acquisition characteristics this amplitude error can dominate the error due to
