Greens Function for Migration
The Greens functions for the equations of zero-offset and non-zero offset migration
are derived under the far-field approximation.
By specifying a homogeneous velocity model with irregular layers, these Greens functions
can be used to quickly compute the migrated section without having to
compute the forward modeled data. This enables the
rapid evaluation of how different source-receiver geometries
affect the migrated section.
Future work should explore the extension of this Green's function to inhomogeneous
summed prestack migrated sections, discrete arrays, waveform inversion and remigration.
