Abstract

Amplitude analysis (such as for amplitude-versus-offset effects) requires a true-amplitude correction at each process stage, including the dip moveout (DMO) process. The well known DMO operator is the "smile" smear, derived by Deregowski and Rocca (1981). In this note we continue their geometrical-optics approach to obtain the amplitude on the operator they derived. The proposed solution is based on ray theory.
