Angle-dependent reflectivity recovery by planewave synthesis imaging

Jun Ji

In this paper I compared imaging conditions of three different prestack migrations in terms of angle-dependent reflectivity recovery. The imaging conditions compared are shot profile migration with conventional imaging condition, de Brduin's imaging condition, and planewave synthesis imaging. The conventional imaging condition can be applied to any reflector geometry and to arbitrary velocity, but it recovers only diagonal component of the reflectivity matrix. de Bruin's imaging condition recovers full reflectivity matrix but has difficulty in implementing for arbitrary reflector geometry and under variable velocity. Planewave synthesis imaging takes advantages from both conventional and de Bruin's imaging condition.
