REVERSE-TIME MIGRATION SYSTEM AND METHOD IN ELASTIC MEDIUM APPLYING ABSOLUTE VALUE FUNCTION FOR IMPROVING QUALITY OF SUBSURFACE STRUCTURE IMAGE

摘要

The present invention relates to a reverse-time migration system and method in an elastic medium applying an absolute value function for improving the quality of a subsurface structure image and, more particularly, to a reverse-time migration system and method in an elastic medium, capable of improving the accuracy of the subsurface structure image by applying the absolute value function in the migrated image and minimizing the change of a waveform by separating a wave field using a relation between stress and a displacement.;COPYRIGHT KIPO 2016
