| Abstract | 为了更加直接有效地通过调整副面位置来提高双反射面天线的电性能，基于机电耦合思想，建立了副面位置调整量与远场电性能间的直接关系式，分析了副面横向和纵向位置偏差的影响。采用优化方法建立了副面位置调整量优化模型，获得了多个仰角时的副面最佳位置。为实现全仰角范围副面位置的实时调整，对多个仰角副面位置调整参数进行了参数拟合。以 26 m 天线为对象进行了案例分析，其结果表明采用文章所述方法能够直接有效地获得不同工况时的副面最佳调整参数,并实现电性能的最优化，对天线结构重力变形进行有效地主动补偿。 |
| Other Abstract | To improve the electromagnetic performance of the dual-reflector antennas more directly and effectively by adjusting the subreflector position, the direct relation between subreflector position adjustment parameter and electrical performance is developed based on electromechanical couple theory. The influence of the lateral and axial deviation of subreflector position is analyzed. The optimization model of subreflector position adjustment parameter is established, and then the optimal subreflector position parameters at some elevation angles are obtained, which are fitted to achieve subreflector position real-time adjustment at the all elevation angles range. The method is applied a 26mreflector antenna. Result shows that the proposed method can obtain the optimal subreflector adjustment parameters directly and effectively, optimize electrical performance, and active compensate effectively the antenna structure gravity deformation |
