Abstract
There is a method for generating a final image of a subsurface of the earth. The method includes receiving measured seismic data d of the subsurface; selecting an objective function E that is function of a reflectivity r of the subsurface; and calculating, in a processor, the reflectivity r based on the measured seismic data d, the objective function E, simulated data {tilde over (d)}, a modeling operator M from a reverse time demigration (RTDM) process and an imaging operator Mfrom a reverse time migration (RTM) process.
