f (w-k) Linearized inversion of 3D multioffset data - Background reconstruction and AVO inversion

Seismic reflection data are usually proceseed using 3D DMO plus zero-offset inversion or a series of 2D multioffset inversions. The 2D multioffset inversions do not work for lateral scattering due to inhomogeneities located outside the plane where the process is applied. The 3D DMO plus zero-offset inversions work properly only if the background medium is assumed homogeneous.
