An outfield testing method for phased array radar antenna polarization feature

为了解决相控阵雷达天线极化特征的外场测量问题,研究了极化的幅相测量法和斜天线测试场的布局方法,设计了基于双通道接收技术的相控阵雷达天线极化特征的一种外场测试方法。给出了应用该种方法的测量装置、测量布局、测量内容、测量步骤,分析了测量误差。该种测试方法在相控阵雷达天线极化特征测试任务中得到成功应用,为某武器系统的研制提供了准确的测量数据和宝贵的研究资料。

In order to find a solution to outfield-measure phased array radar antenna polarization feature, amplitude and phase measurement for polarization and arrangement for oblique antenna ~esting field were studied. Afterwards an outfield testing method for phased array radar antenna polarization feature based on double-channels receiving technique was designed. For using this method, measuring equipment, measuring distribution, and measuring content, measuring process were given, and measuring error was analyzed, and a typical figured mode for dealing with measuring result was recommended. The testing method in this paper was gained successful application when some polarization feature testing mission was carried. It offered accurate measuring data and valuable studying information for some armament system was developed.
