Gaussian packet prestack depth migration

Karel Zacek

Summary

We present a complete algorithm and the first complete 2-D acoustic numerical examples of a brand new imaging method operating in the common-shot domain - the Gaussian packet prestack depth migration. The main advantage of our method over the methods based on Gaussian beams is a direct relation between the regions in the common-shot gather and corresponding regions in the migrated section. Thus, the Gaussian packet prestack depth migration is especially suitable for a target-oriented imaging.

Keywords

Gaussian packet, Gabor function, prestack depth migration, target-oriented imaging, multi-valued travel time, common-shot gather.
