Abstract: This paper briefly describes the concept of systematic errorsand random errors for reflector antenna.Two kinds of compensation methodfor large reflector antennas are introduced,i,e,the array feeds compen-sation method and the refocusing and subreflector matching method.The keypoint of mechano-electrical unification design for reflector antennas is brie-fly described.
