The interpretation of ground penetrating radar (GPR) signals requires a good knowledge of the electromagnetic wave generation and propagation phenomena. Both visual interpretation of the radar sections and numerical processing of the echoes are based on theoretical considerations aiming to explain the wave scattering mechanism from simple structures and wave reflections from subsurface anomalous bodies. Actually, GPR involves a very complex phenomena, because the radar antenna emits very close to a random media, eventually stratified and with scatters embedded in it. Responses from single target, in free space and into the ground, are investigated using different reciprocal antenna positions of bistatic georadar OYO YL,R2 with 600 MHz antennae (TE, TM mode and cross‐polarized). The same data acquisition approach was used in an archaeological test site, containing dromos chamber tombs (Sabine Necropolis of Colle del Forno). The measurements, in this case, were carried out with the same georadar system. The experimental and field results are compared in order to understand the significance of the polarization effects. In this work, the experimental configuration, the field and elaborated data are shown. Some considerations about different field instrument configurations are presented.
