Distributed passive radar imaging has been an emerging topic in radar imaging society because of its low-cost, increased-survivability and robustness. In the inverse problem of distributed passive imaging, location of receivers affects imaging quality a lot, while illuminators of opportunity remain to be uncontrollable. Therefore, we investigate the problem of receiver disposition optimization and...
Although phased-array antennas are widely used in communication, radar, and navigation systems, its beampattern is a function of angle only and thus there is no range information. To circumvent this limitation, we design a frequency diverse array (FDA) antenna system for range-angle imaging of targets. Our approach exploits the nonuniform FDA as the transmitter to provide range-dependent beampattern...
