f GPR Imaging with Focused Migration

The technique of migration is often used with Ground Penetrating Radar (GPR) to image subsurface targets. However, GPR data sets can have distortions that degrade the imaging process significantly. These distortions can emanate from uneven sampling on the surface or an unknown velocity distribution in the subsurface. Perhaps the most common distortion is created by inhomogeneities in the subsurface that are not of interest. This distortion manifests itself as an aberration in the wavefront recorded at the surface.
