Abstract

The various analytic schemes for performing a wavefield extrapolation or seismic migration from measurements upon a planar surface within a constant velocity medium are inherently related to each other. All schemes can be derived from a simple plane-wave representation of the recorded wavefield. One scheme that is very easy to conceive is based on the Radon transform. It enables one to perform a wavefield extrapolation or seismic migration by a filtered projection and a back projection of the recorded wavefield. This reveals that the theory of seismic migration as well as the theory of seismic tomography are very closely related to each other.
