N2 - While reverse-time, prestack migration (RT-PSDM) has become a common imaging method in seismic exploration, its use has remained relatively limited in GPR applications. Antenna radiation patterns have a significant impact on ground-penetrating radar (GPR) data amplitudes. Radiation patterns must be properly accounted for in quantitative amplitude analysis. Here, I use a full wave-equation RT-PSDM algorithm to investigate the potential to correct multi-offset, ground-penetrating radar (GPR) amplitudes for antenna radiation pattern effects. By including the earth-air interface in the source wavefield estimation, the radiation pattern effect is removed at the reflecting interface. Further, geometric spreading and attenuation due to conductivity are naturally corrected in the RT-PSDM framework.
