| Abstract: | CBERS remote sensing satellite ground receiving system is X/S two band autotracking system.The operation principles of the antenna and feed are described in this paper. The dichroic subreflector combined feed technique is used.The X band feed consists of five horns with SCM autotracking method,located near the reflector vertex in a Cassegrain configuration,The S band feed consists of a five element,planar array with ESCAN autotracking method,located at the prime focus of the main reflector. |
