Abstract

We propose a phase-shift extrapolation operators extending the straight-ray approximation to locally parabolic rays for depth variations of slowness and also for lateral deviations. This construction leads to second-order accurate wave-propagations operators. Its improvement is verified by numerical experiments, where the synthetic test demonstrate that the proposed method corrects straight ray approximations.
