Abstract A point-source seismic recording can be decomposed into a set of plane-wave seismograms for arbitrary angles of incidence. Such plane-wave seismograms possess an inherently simple structure that make them amenable to existing inversion methods such as predictive deconvolution. Implementation of plane-wave decomposition (PWD) takes place in the frequency-wavenumber domain under the assumption of radial symmetry. This version of PWD is equivalent to slant stacking if allowance is made for the customary use of linear recording arrays on the surface of a three-dimensional medium. An imaging principle embodying both kinematic as well as dynamic characteristics allows us to perform time migration of the plane-wave seismograms. The imaging procedure is implementable as a two-dimensional filter whose independent variables are traveltime and angle of incidence.
