| Abstract(in English) | We present a compact polarimetric ground penetrating radar (GPR) system, which consists of a circularly polarized spiral antenna for the transmitter and two orthogonally oriented Vivaldi antennas for the receivers. The combination of a spiral antenna and a Vivaldi antenna is demonstrated to operate in an ultra wideband, to have small antenna dispersion and to possess better antenna isolation. We carried out a laboratory experiment on a sandpit to demonstrate the improved performance of the new GPR system over the conventional one in detecting linear subsurface targets. We buried five metal wires at a depth of 15 cm in a sandpit, respectively at different angle to the survey line. A conventional GPR survey conducted by a commercial single-polarization GPR system may lose the sight of a wire when it is orthogonally oriented to the antenna polarization direction. In contrast, the proposed polarimetric GPR system can detect a metal wire by a single scan line, regardless of its strike direction. |
