ABSTRACT

The reverse-time migration imaging condition can be improved by computing the reflection strength at each subsurface point as the zero lag value of the deconvolution of the receiver wavefield by the source wavefield. I show that by using this approach it is possible to eliminate image artifacts due to wavefield multipathing through velocity anomalies. I also show that it has the advantage of handling better amplitudes during imaging.
