A stable and practical implementation of least-squares reverse time migration
Geophysics | Yu Zhang, Lian Duan, Yi Xie © 2015 SEG | January
By adapting reverse time migration (RTM) and demigration as the migration and modeling operators to maximize the crosscorrelation between the simulated and the acquired seismic data, we introduced a new practical least-squares RTM (LSRTM) scheme and derived a steepest descent method in seeking the ...
