## ABSTRACT
Illumination problems caused by finite-recording aperture and lateral
velocity lensing can lead to amplitude fluctuations in migrated
images.
I calculate both model and data-space weighting functions that
compensate for these illumination problems in recursive depth
migration results based on downward-contination.
These weighting functions can either be applied directly with
migration to mitigate the effects of poor subsurface
illumination, or used as preconditioning operators in iterative
least-squares ( |
