P091 MULTI-FREQUENCY AND MULTI-AZIMUTH POLARIMETRIC GPR FOR BURIED UTILITIES DETECTION Abstract 1 We exploit multi-frequency and multi-azimuth polarimetric GPR techniques to detect and characterize linear targets for the study of urban technological networks. The selected targets are buried pipes of different materials and the GPR measurements are performed in TE and TM co-pole antenna configurations. We test the methods in controlled (sandbox) and in real conditions. We further compare Finite Difference Time Domain (FDTD) numerical simulations with real data obtained from the sandbox in order to estimate the electromagnetic (EM) properties of the target (pipe). Azimuthal surveys performed in co-pole
