Conclusion

In this paper, we generalize the conception of source-receiver migration. Generalized source-receiver migration works for arbitrary sources. It is not restricted to a point source and it is not survey-sinking, but rather the downward continuation of the cross-correlation between the source and the receiver wavefield. We prove the equivalence between shot-profile migration and source-receiver migration for arbitrary sources, given the assumption that the imaging condition is cross-correlation and the wavefields are propagated by one-way wave equation downward continuation.
