Abstract :
Various methods of determining the beam efficiency of large space borne reflector antennas used for remote sensing of the atmosphere are reviewed and new developments described at the 110-190 GHz range. Measurements of radiation pattern on a far-field or on a compact range are studied. Also alternative methods are studied: beam efficiency measurement with hot and cold loads on a compact range and calculation of the beam efficiency of the reflector antenna using measured feed phase and amplitude patterns and accurate surface information of the reflector
