Application of the finite-difference reverse time migration (FD-RTM) to ground penetrating radar (GPR) data may generate high-resolution imaging for complex geologic bodies. However, in conditions of complex topography, due to topographic roughness it is very difficult to get clear images of near-surface internal structure with the traditional approach of “static correction + flat datum migration”...
2D crosshole ground penetrating (GPR) full-1 waveform inversion (FWI) has shown superior resolution 1 compared to ray-based inversion tomograms for synthetic and experimental data. To invert measured 3D data with a 2D j model that has a reduced geometrical spreading and assumes infinite source and receiver dimensions perpendicular to the 2D inversion plane, the Bleistein transformation can be used...
