WebAzimuth moveout (AMO) is by de nition an operator that transforms common-azimuth common-o set seismic re ection data to di erent azimuths and o sets2. A constructive approach to AMO was proposed by Biondi and Chemingui (1994). Ac-cording to this approach, an AMO operator is built by cascading the dip moveout WebTrue‐amplitude seismic imaging produces a three dimensional (3-D) migrated section in which the peak amplitude of each migrated event is proportional to the reflectivity.
