Abstract
The forward model of prestack data that we use in our seismic inversion project DELPHI (Berkhout and Wapenaar, 1990) is based on a number of matrix multiplications. In its simplest form, (i.e. after pre-processing), it is given by P = W RW+S+ Where S+ contains the downgoing (source) wave fields at the surface, W+ describes downward propagation into the subsurface. W describes upward propagation to the surface and, finally, P contains the upgoing wave fields at the surface
