Finding the Amplitudes of Migration Hyperbolas from the Kinematics

In migration and DMO, the kinematic problem is easier to solve than the amplitude problem. Where a purely analytical approach is normally used to obtain the amplitude of a migration operator, we attempt to obtain amplitude information by combining an assumption of a at spectrum with the kinematical formulation. This hyperbola whitening is done with a 2-D prediction-error lter. This technique is applied to three hyperbolas: a kinematic-only hyperbola, a amplitude-corrected hyperbola, and an amplitude-corrected hyperbola with a half-derivative lter. The results show that the assumption of a at spectrum connicts with the existence of an evanescent zone, creating unresolved diiculties.
