摘要

本文研究了一种轴对称双反射面天线的成形过程，以控制孔径场的振幅和相位。副反射面和主反射面的生成是通过连续的圆锥截面串联形成的。为了说明该算法的有效性，在几何光学原理下，形成了一个轴位移的卡塞格伦结构，以提供均匀的孔径。利用矩量法提供的电磁分析对结果进行了验证。

A New Technique for Shaping Axis-Symmetric Dual-Reflector Antennas Using Conic Sections

This work investigates a neiv procedure for the shaping of axis-symmetric dual-reflector antennas to control the amplitude and phase of the aperture-field. The generatrices of sub- and main-reflectors are shaped through consecutive concatenation of conic sections. To illustrate the efficacy of the algorithm, an axis-displaced Cassegrain configuration is shaped to provide an uniform aperture mumination, under Geometrical Optics principles. The results are validated using the electromagnetic analysis provided by the method-of-moments.
