We present an approach for the Through-Wall-Imaging based on a simple model of the scattering problem involving few unknowns, exploiting effectively the a priori in-formation on the scenario and using a global optimization approach, relying on Legen-dre-Fenchel Transforms, tailored to fast, parallel implementations on Graphic Processing Units (GPUs).
Experimental results are presented against X-band data collected in a realistic scenario made of a wall of Ytong concrete blocks and a metallic cylindrical scatterer.
