ABSTRACT

Shot-profile migration and source-receiver migration seem different, but the image and Common Image Gather they obtain is the same. In this paper, we prove that shot-profile migration and source-receiver migration are equivalent, assuming that the imaging condition is cross-correlation and the method for propagating the source and receiver wavefields is a one-way wave equation. This is achieved after generalizing source-receiver migration to arbitrary sources.
