Abstract :
Spaceborne synthetic aperture and scatterometer radars currently under development for Earth remote sensing may require the provision of ground calibration targets with very large scattering cross-sections. One way of providing these would be to adapt existing parabolic radio telescopes or satellite Earth station antennas by replacing the feed by a metallic sphere. A dichroic surface would facilitate tracking.
