SHAPE-RECONSTRUCTION AND QUANTITATIVE ESTIMATION OF ELECTROMAGNETIC AND PHYSICAL PROPERTIES FROM GPR DATA" STATE OF THE ART AND OPEN ISSUES

The design of GPR data processing tools aimed at reconstructing in a quantitative way the characteristic features of a monitored region is an open and challenging issue. This not trivial task requires the development of imaging techniques based on sophisticated models capable of properly describing the involved scattering phenomenon as well as the probing wavelet. This paper aims at describing briefly some of the most relevant advancements reached in the last years. Moreover, some open challenges are traced in order to give some hints to address future works.
