| 英文摘要 | A determining method of relaxed deformation error for large antennas main reflector that considers the compensation of the shaped subreflector is proposed. Using the orthogonal functions, describe the independent error items of antennas' reflector that make it universal, and combining the approximate electrical field calculation and the compensation functions of shaped subreflector establish the relaxed error determination model for main reflector deformation. To solve the model that includes internal and external optimization, the path length error iterative compensation method is used to fast design the shaped subreflector. And for the external optimization, a dichotomy, taking into account the monotonic relationship between reflectors error and antennas gain, is designed to iteratively obtain the relaxed error items' upper, lower bounds and the convergent results. The 110 m standard and 80 m offset reflector antennas working at 115 and 30 GHz, respectively, with two classic deformation error types, are taken as examples. The excellent results obtained by a few iterations showed the effectiveness of the proposed model and the corresponding fast solution method, and both types of the two type errors are relaxed by over tens and even hundreds of times, indicating the enormous potential of the shaped subreflector for compensating the main reflector deformation. |
