| 摘 要： | 本文基于物理光学球面波展开法，提出一种计算抛物面天线支杆对其方向图影响的简化方法，文中导出了计入支杆散射的天线辐射方向图的解析表达式，并给出了支杆对其方向图旁瓣电平影响的计算实例，数值结果表明，本文所提出的新方法不仅计算结果精度高，而且所需计算机容量小，运算速度快，可应用于天线工程设计。

| Abstract: | Based on PO/SWE method, a simplified approach for calculating radiation patterns of the paraboloidal antennas with struts is presented. A set of closed-form formulas for the calclation is derived,and numerical results for the effect of struts on sidelobes of radiation patterns are given. The calculation results show that the new approach has t lot of features such as high accuracy. small storage capacity and highspeed etc., so as to be a useful method for antenna analysis and design |
