SDR SAR Target: Corner Reflector and Communication

This paper presents a novel target, based on software-defined radio (SDR) technology, that allows the support of remote sensing processes and enables a transparent communication link in synthetic aperture radar (SAR) systems. Nowadays the integration of communication services in technologies that are not developed for this purpose can be an interesting solution for the increasing communication demand. The novel target acts in two different ways for SAR systems: as software-defined corner reflector (SDCR) for localization and calibration support, but also as SAR target to integrate a transparent communication link for target identification and tracking.
