摘要：

Based on the deterministic basis of the surface accuracy for the antenna, computational modeling with the semi-optical path difference as minimum value was established. As a result, a software program for surface measurement and adjustment of reflector antenna was developed. The surface accuracy of the high-precision reflector antenna was measured and antenna feed was positioned using free fixing. The surface accuracy of central zone for the large parabolic reflector antenna is 26 μm. Electrical performance test results show that the compact range has excellent electrical performance in the frequency of 26~110 GHz, and verify the correctness of the mechanical accuracy test results. This technique not only improves the efficiency of mechanical alignment significantly, but also possesses potential applicable value in engineering.
