摘　　要：C-RAM系统要求雷达天线波束具有半球覆盖的特性,可以采用的天线有圆锥台、圆柱加顶锥、多棱锥、多面阵等结构形式。本文针对这几种天线对其天线有效面积、天线总面积与天线结构形状之间关系进行了研究分析,得出了C-RAM系统中圆锥台天线的形状性能较优的结论。Counter rocket, artillery and mortar （ C - hemispherical coverage. Selectable structural forms top, pyramid, multi - face array, etc. For all these RAM） system requires that radar antenna should be capable of of antenna include： truncated cone, column with a cone on structural forms of antenna, relation between effective area and total area of antenna and their structural form are studied and analyzed, conclusion obtained is that performance of the truncated cone antenna is much better.

关 键 词：C-RAM 天线有效面积 圆锥台天线
