| 摘 要： | 飞行器头部的天线是鼻锥方向的一个强散射源,它对目标雷达截面的贡献包括了普通的结构散射项和再辐射引起的模式散射项,后者是天线作为一个加载散射体所特有的。本文给出了这两项雷达截面的散射机理和分析计算方法,并提出了减小天线雷达截面的若干技术途径及其实际效果。

| Abstract: | Antennas in aircrafts give large contributions to the radar cross section (RCS) of target at particular aspects, which include both the common structural and antenna-mode components, the latter is a special character of loaded scatierers due to the re-radiation. In this investigation, the scattering mechanism and analytical computation methods for the two RCS components of antennas are discussed, and some technical ways as well as their effects for antenna RCS reduction are proposed. |
