On the reconstruction capabilities of microwave tomography imaging

Ground Penetrating Radar (GPR) systems are non-invasive diagnostic tools able to provide high resolution images of the inner structure of the probed spatial region. Owing to this capability, GPR systems are nowadays more and more considered in a large number of applications as geology, archaeology, civil engineering, demining, and so on. In particular, beyond the most common down-looking systems, airborne and forward-looking GPR are gaining attention as subsurface imaging tools able to survey wide, possibly non accessible, areas and/or to assure a standoff distance between the operator and the targets.
