An UWB ground-coupled radar has been designed to operate from 460 MHz to beyond 4 GHz and essentially for civil engineering applications. Full-wave modeling using the FDTD approach has allowed to study in details the antenna radiation characteristics in air, in the presence of a soil and as a constituent in a bistatic GPR system. The polarization diversity in the E and H-planes is an important aspect...
In the field of civil engineering, sounding the layers is classically performed using standard ground-penetrating radar (GPR), whose vertical resolution is bandwidth dependent. The layer thicknesses are deduced from both the time delays of backscattered echoes and the dielectric constants of the layers. In contrast with the conventional spectral analysis approaches, we propose in this paper to use...
