A New Feed Brace System in Single Reflector Compact Antenna Test Rang

Abstract:

To solve problems of the traditional feed brace in single reflector compact antenna test rang, such as difficulty in position adjustment and the feed polarization manual switching, mechanical structure and position adjustment mechanism of feed brace system are designed, based on principle of feed positioning. The new feed brace system weight is lightened with same intensity. Function of precision rotation around axis of feed horn is realized. Control system software is developed. Two control modes, onsite and remote, are provided. Laser tracker is used to locate feed phase center in high-precision when feed brace system is installed on site. The new feed brace system has been applied in some single reflector compact antenna test range and its precision meets the requirements.
