40th ESA Antenna Workshop, 8-10 Oktober, 2019, Noordwijk, The Netherlands
Radio-telescopes or ground-station antennas can, if pointed, act as a radar target with high radar cross-section (RCS). Space-based Synthetic Aperture Radar (SAR) data confirmed it at 5:3GHz for a modified ground-station antenna. Operational ground-s
