本文根据双反射面天线结构及其电气性能的特点,基于几何光学原理,应用拓扑图论有限元分析方法及主反射面预调角的思想,求得预优工作位置上的最优主面形状。进而基于物理光学原理,应用场相关法及最优化计算方法,求得预优工作位置上的最优副面形状。从而实现了机电统一设计双反射面天线表面形状的目的。与传统的设计方法比较,它具有天线设计效率高、安装调整量少等明显优点,故是一种简便易行的新的设计方法。
Based on the geometrical optics principle and the idea of finite element analysis of the topological graph theory and the angle of the primary reflector, the optimal primary surface shape of the pre-optimized working position is obtained according to the structure of the double reflector antenna and its electrical performance. . Then based on the principle of physical optics, the application field correlation method and the optimal calculation method, the optimal secondary shape of pre-optimal working position is obtained. Thus realizing the purpose of unified design of the surface shape of the dual reflector antenna by the electromechanical. Compared with the traditional design method, it has the obvious advantages of high antenna design efficiency and small installation and adjustment, so it is a new and easy design method.
