Migration Operators and Impulse Responses

Explore the intricacies of migration operators and impulse responses in the context of symmetrical and asymmetrical velocity fields. Understand how point diffractors, Kirchhoff time migration, and lateral variability affect energy propagation. Delve into the complexities of local velocity fields and depth migration with non-hyperbolic operators.
