Migration (q.v.) or imaging accomplished by application of the wave equation in one of several ways: in the time domain by a finite-difference method, in integral form (Kirchhoff migration), in frequency or wavenumber domains (after a 2D transform into frequency-wavenumber domain; frequency-domain migration), or some combination of domains. See Sheriff and Geldart (1995, 267–268, 326–335).
