Abstract：In order to make the best of the diffractions to illustrate the small-scale structures (faults,pinch-outs,fractures,salt flanks,etc.),we introduce in this paper the anti-stationary phase filter into depth Gaussian beam migration with the help of dip-scanning and kinematic/dynamic ray tracing.So we develop a diffraction imaging method in the depth domain driven by anti-stationary phase strategy.Tests on Sigsbee 2A model and field data prove the accuracy and validity of the proposed method.
