Zusammenfassung:At TNO an innovative concept to obtain inside building awareness 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. These scatterers can be reconstructed from the data using an overcomplete dictionary and sparse reconstruction. In this paper, the reconstruction algorithm and some results will be presented.
