Using polarimetric GPR antenna to characterize hidden cylinders

The recent appearing of multi-component GPR antennas in the research and market fields is attracting interest towards the possibility to exploit polarization diversity in order to gain more information on the probed scenario. In this framework, based on a forward model, we investigate the potential of discerning the electromagnetic nature of cylindrical targets staring from B-scan measurements. The study is carried out via a FDTD numerical analysis and is supported by analytical results referred to the 2D case. The preliminary obtained results suggest that is actually possible to discriminate conducting and dielectric circular cylinders from multi-component GPR B-scans. Experimental results are also provided.
