| description | It is well known that reverse-time migration is capable of correctly
imaging multiply scattered energy. To do this, one of the interfaces
from which the waves scatter must be included in the background velocity
model. In a one-way framework this requirement is avoided
by iteratively forming images of higher-order scattered waves. These
techniques use an image made with singly scattered waves to estimate
the locations of some of the reflection points in a multiply-scattered
wave, from which the location of an additional scattering point is
determined through standard imaging techniques. This removes the
requirement that a single multiple-generating interface be identified.
Here we extend this technique to reverse-time migration using results
from several recent studies linking standard and extended imaging
conditions to interferometry. This results in a method to generate images
with multiply-scattered waves using the full-waveform imaging
techniques of reverse-time migration and the iterative imaging formulations
of scattering series in a one-way framework. |
