Abstract

We propose an approach for preserved amplitude wave equation migration in angle domain. This approach is based on shot-receiver wavefield continuation, and successive buildings of common image gathers in depth offset domain, then angle domain. Imaging formulas are derived in 2D for acoustic reflection coefficient and square slowness perturbation, standing as specific weighted slant-stacks from offset domain to angle domain. An application on the Marmousi dataset is presented, with comparison to preserved amplitude multi-arrival ray-based migration.
