Creating virtual vertical radar profiles from surface reflection Ground Penetrating Radar data

We present a three-dimensional scheme that can be used to compute a vertical radar profile from reflection data measured at the surface. This is done by first constructing a focusing wavefield, which focuses at the chosen location in the subsurface that is then the virtual receiver location for the vertical radar profile Green´s function. Because the up- and downgoing parts of the Green´s function are retrieved separately, these are very useful for imaging and inversion. We show with a numerical example that the method works well in a two-dimensional configuration.
