Landmine detection using ground penetrating radar and polarimetric Synthetic Aperture Radar

In this paper, the data processing based on polarimetric features extraction from Synthetic Aperture Radar (SAR) processed data is discussed. For this purpose, fully polarimetric data were collected using the ultra-wideband Ground Penetrating Radar (GPR) and quad ridged horn antenna. The measurement of plastic landmine, metallic pipe and rocks buried in the sand was carried out so that three dimensional data correction and visualization could be applied. Since the landmine is detected in the presence of a metallic target, a standard GPR processing does not lead to satisfactory results. Therefore, polarization and orientation features were obtained by means of the polarimetric decomposition in order to classify and detect various objects.
