M. Glöckner and D. Gajewski: Diffraction Separation with Migration Apertures

Glöckner et al. present a diffraction separation based on migration apertures. Apertures in the range of the first Fresnel zone favour reflections whereas large apertures enhance diffractions. Differences are visible in the migrated coherence section and can be used for a masking and final demigration to obtain diffraction only pre stack data. The proposed method is applied to synthetic data. It shows good separation results for simple data but also the limitations when data is more complex.
