| 摘 要： | 利用复射线近轴近似法和集合射线法,可以十分简便地分析天线罩的电磁传输特性和散射特性。本文以二维圆柱形天线罩为例,分析了介质罩对罩内雷达天线性能的影响;计算了天线罩引起的传输系数和角跟踪性能的变化,以及天线罩的附加雷达散射截面;讨论了射线参量及天线、天线罩参量对分析计算精度的影响。数值结果表明,这种分析方法可以显著地简化天线罩优化设计,并可适用于其它多种型式的天线罩。

| Abstract: | EM transmission and scattering characteristics of radome may Conveniently be analyzed by complex ray paraxial approximation and collective ray methods. 2-D cylindrical radomes are analyzed and calculated, including radome transmission coefficient, radar angular track property and radar cross-section of radomes, as well as the effect of ray parameters and antenna-radome parameters on computation accuracy. It is shown that this method can be used to simplify optimization designs for many kinds of radomes. |
