Abstract The reconstruction of three-dimensional (3-D) velocity variations from finite-offset scattering data is formulated. Reduction to the limiting cases of zero and small offset distances as well as the case of one-dimensional (1-D) stratification is given. An inherent increase in complexity is cited and interpreted. The relationship of the proposed inversion to the F-K migration is discussed.
