Conventional GPR use a single antenna mode for transmission and reception, resulting in a response only to Co-Polarization signal. However, we expect that more polarmetric information can be obtained if Cross-Polarization signal is also measured. So we developed a polarimetric antenna array using Vivaldi antenna elements, due to their wide bandwidth and non-dispersion nature. The paper describes design and realization of the polarimetric antenna array accommodated on the full-polarimetric GPR system. Two groups of experiment have been performance. The first group is concerned with the standard dihedral which is made of two orthogonal conducting plates as the targets to prove the availability and accuracy of the polarimetric Vivaldi antenna array. The second group is using a metallic cylinder as the target. The results of experiment are shown in this presentation that Co-Polarization and Cross-Polarization information can be obtained for each transmission and help us to identify target attribute such as direction. |
