3D Imaging of Buried Dielectric Targets with a Tomographic Microwave Approach Applied to GPR Synthetic Data

Figure 2

GPR B-scan synthetic radargrams from our numerical setup for a basalt cube of 10 cm side, buried 10 cm deep from an air/sand interface (details on the other physical parameters are in the main text for this and the subsequent figures). Grey-scale received-signal amplitude in time versus longitudinal scanning position along , for three parallel lines at different : (a) line 1; (b) line 5; (c) line 8. Here and for all the other synthetic radargrams (Figures 35), the scatterer is located in a central position along .
