Ka-band groundstation antenna aspects for deep space telecommunication and radar

The paper discusses considerations for a large 35 m ground-station antenna operating in Ka-band with a powerful amplification stage. It could give additional functionality for radar applications (investigations into imaging by inverse synthetic aperture radar (ISAR) of objects in space or Near Earth Objects (NEO)) and for Deep Space Telecommunication. Detection of space debris more near to Earth would obviously benefit from high power sources in Ka-band. However, the near-Earth target scenario is better handled with another type of antenna (phased array, mono/bi-static and other parameter scenarios).
