本文构造拟里兹广义插值模型,逼真地描述天线主反射面的变形状态,在此基础上,应用光学设计中的光线追迹公式、象质评价函数、象差自动平衡概念和方法,以及建立的电磁能量的匹配原则,就能更精确地计算确定副反射面或馈源的最佳匹配位置,实现天线反射面系统的高性能调整。这种方法具有一定的应用价值。
This paper constructs the Friedrich generalized interpolation model, which realistically describes the deformation state of the main reflecting surface of the antenna. On this basis, we apply the ray tracing formula in optical design, the evaluation function of the image quality, the concept and method of auto-balancing aberration, The matching principle of the electromagnetic energy can more accurately calculate the optimal matching position of the subreflector or the feed and realize the high performance adjustment of the antenna reflection surface system. This method has a certain application value.
