| 摘 要： | 以复源点所产生的高斯波束场来模拟高效率馈源ＨＥ＾－１１口径的辐射，馈源辐射近区内环焦副反射面的散射场可由复射线追踪法求得。作者在该文中给出馈泊位置及馈电方向沁定量通用的费马原理表达式及散射场表达式，通过数值计算给出散射场分布结果。这一方法可用于环焦天线的分析与优化设计。

| Abstract: | With a simulation of the radiation from HE 0 11 field distribution in aperture of high efficiency feed horns by Gaussian-beam field from a point source with complex coordinates, the scattering of ring-caustic subreflector near the feed is analyzed by complex ray tracing. In this article, the general Fermat principal equation and the scattered field are derived where the location and the radiation direction of the feed horn may be arbitrarily installed. Numerical calculations are made to give a result of scattering distribution, and this method is proposed to give help in analyzing and designing of antennas with ring caustic subreflectors. |
