文中介绍了一种运用于风廓线气象雷达的双极化相控阵天线系统,通过双极化天线单元的分离式设计以及馈电网 络分层架构,使得天馈系统结构紧凑,连接形式简洁;然后对分离式双极化天线单元进行了仿真,分析其扫描驻波并最终 确定了2种极化辐射单元的位置关系和具体尺寸。最后给出了天线阵列实测的典型技术参数和方向图。

A dual polarization antenna array which is used in wind profiler is introduced in this paper. It uses a dual-polarization element with separated configuration and a two-storied feed network to achieve a compact configuration and a simple connected mode. Then we validated the scanning VSWR of the element by simulation and determined the dual-polarization element's specifically structure. The tested parameter and the pattern of the antenna array are introduced in the end.
