| Zusammenfassung |
| The ever growing range of applications of ground penetrating radar (GPR) motivates the need
of developing efficient measurement systems combined with effective data processing
methods. On the one hand, advanced GPR measurement systems require to accurately model
the physical effects occurring between the antenna structure and the medium. On the other
hand, the GPR device should provide a reliable reconstruction of the properties of the targets
under an inspection to a common user. In this work, a novel GPR system was tested for
the imaging of buried structures. First of all, the acquired experimental data were
pre-processed with a proper calibration technique for removing antenna effects. After that, a
reconstruction of a hidden structure was obtained by means of both qualitative and
quantitative electromagnetic inverse scattering methods. In particular, while the
qualitative techniques aim at reconstructing only specific features of the targets (e.g.,
location, shape), the proposed quantitative method has the challenging goal of the
complete electromagnetic characterization of the buried structures. The performance of
the new system was evaluated in different operating conditions with promising
results.
