Abstract: Systems and methods for compensating for spatial and slowness or angle blurring of plane-wave reflection coefficients in imaging. A wave field may be determined at a reference depth proximate to a reflector for a shot record. A receiver-side blurring function may be determined at the reference depth. An aggregate blurring function may be constructed based at least partially on the source wave field and the receiver-side blurring function. A plane-wave reflection coefficients may be determined based at least partially on the aggregate blurring function.
