On the basis of the commonly used antenna pattern measurement method, is the size of a large array antenna taken into consideration, and designed a set of array antenna pattern testing method in an outdoor test field. According to this method, the array antenna pattern of a particular model of aircraft is firstly tested. Then the radiation pattern of the pitch surface is measured and compared with the theoretical simulation results thus proving the accuracy of the experimental program. Finally, the experimental error is analyzed.%在常用天线方向图测量方法的基础上,考虑大型阵列天线尺寸大的特殊性,并且结合实际测量条件,设计出一套在室外测试场中阵列天线方向图的测试方法.按照此方法,对某型号飞机的阵列天线方向图进行测试.测得其俯仰面辐射方向图后与理论仿真结果对比,论证实验方案的准确性,并对实验误差进行分析.
