摘　　要：基于圆形阵列天线特点,提出了一种多波束扫描方式。该扫描方式在最大化发挥圆形阵优势的同时具有了较高的扫描效率,可满足雷达发展的需求。基于耦合单元方向图,对圆阵方向图进行优化,计算结果表明方向图性能达到设计指标要求。该方法适用于任意形式单元构成的圆阵方向图综合,可以很好地满足工程设计需求。Based on the characteristics of circular array antenna,this paper proposes a kind of multi- beam scan mode. The scan mode not only maximizes the advantages of circular array, hut also has higher scan efficiency, which can satisfy the requirement of radar development. Based on coupling element pattern, the circular array pattern is optimized. The calculation result shows that the per- formance of pattern can arrive the requirement of design index. The method is suitable for the cir- cular array pattern integration composed by random form element, and can commendably satisfy the requirement of engineering design.
