High capacity imaging using an array of compressive reflector antennas

This paper presents a novel high sensing capacity compressive imaging system, which is capable of imaging human-size targets. The system uses an array of Compressive Reflector Antennas (CRAs) in order to extend the imaging domain of a single CRA. Moreover, the multi-static electromagnetic cross-coupling of adjacent CRAs in the array is used as a mechanism to improve the imaging performance. A physical optics method is used as a forward model; and the Total Variation norm option, in the NESTA software, is used for performing the compressive imaging. Preliminary results show that the system is capable of providing an accurate reconstruction of a tesselated model of a human body.
