Claim One:
1. A method, stored in a memory and executing on a processor, for generating a modeled seismic image based on a reverse time demigration (RTDM) of a seismic depth image associated with one or more seismic sources and one or more seismic receivers, said method comprising: adding a coupling term, based on a reflectivity term acting as a linear source, to an RTDM equation creating a coupled RTDM equation; estimating a pseudo-density function by converting, based on solving a nonlinear inversion, said seismic depth image to said pseudo-density function; stabilizing said coupled RTDM equation by replacing, in said coupled RTDM equation, said reflectivity term with said pseudo-density function to create a stabilized coupled RTDM equation; solving said stabilized coupled RTDM equation and reconstructing wavefields at said one or more seismic receivers based on said seismic depth image, one or more migration velocities and locations associated with said one or more seismic sources; and outputting a modeled seismic image associated with said seismic depth image.
