Least squares reverse time migration imaging with illumination preconditioned based on improved PRP conjugate gradients

Least squares reverse time migration imaging with illumination preconditioned based on improved PRP conjugate gradients

Abstract Least squares reverse time migration (LSRTM) imaging is the one of the most accurate methods for migration imaging at present, and Polak–Ribiere–Polyak conjugate gradient (PRPCG) for LSRTM has the good numerical performance but weak convergence, so we construct an optimization factor to imp...
