Abstract :
At TNO a new concept to synthesize maps of building structures with stand-off, through-the-wall radar has been developed: SAPPHIRE. The system concept exploits particular phase behavior in the 3D radar data to extract dominant scatterers inside a building. The phase relations are extracted from the radar data by using an overcomplete dictionary and sparse reconstruction. In this paper, the reconstruction algorithm and first results will be presented.
