| 摘 要： | 本文论述了运用物理光学、射线理论混合分析反射面天线的过程,确定了混合方法在计算一般反射面天线时的分界区域。同时,以天线口径分布为基础,推导出一种新的场点抽样技术,用以较精确地计算混合方法分界区的场。本文还提出一种反射面天线的精确计算方法:扩展口径面积分法(EAI)。

| Abstract: | In this paper, a hybrid method which combines the physical optics method with the rays theory is used for calculating the radiation fields of the reflector antenna. The boundary point will be found by using of the extending aperture integration (EAI) approach. A new field sampling technique for calculating the fields near the point with more accuracy is presented which can be used when the results calculated by physical optics method and rays theory differ at the boundary point. |
