METHOD OF REDUCING PHASE ABERRATION IN ANTENNA SYSTEM WITH ARRAY FEED

摘要

PROBLEM TO BE SOLVED: To provide a method for reducing phase aberration in an antenna system for a satellite.SOLUTION: An antenna system is configured to receive and/or emit at least a spot beam. The antenna system includes: a reflector 2; an array feed 1 including a plurality of feeds configured to irradiate the reflector 2 in an emission mode and/or configured to receive irradiation from the reflector 2 in a reception mode; a trimming system 3 configured to adjust the position of the reflector 2 with respect to the array feed 1. A method for reducing phase aberration in an antenna system for a satellite includes a step of adjusting the position of the reflector 2 with respect to the array feed 1 in order to correct phase aberration in the spot beam.SELECTED DRAWING: Figure 1
