| 摘 要： | 以天线的空域指向为变化因素来分析研究相控阵天线的空域极化特性,推导了偶极子线性阵列在空域波束电扫时的极化特性.采用三维电磁仿真平台(XFDTD)设计了具有625个单元的平面矩形相控阵天线,计算了天线远场的主极化和交叉极化分量,进而利用空域极化描述子得到了不同波束指向下典型相控阵天线极化特性的变化规律.结果表明:相控阵天...

| Abstract: | Antenna spatial oriented direction is taken as variation to study the spatial polarization characteristic of phased array.The polarization property of electronic scanned linear dipole array is derived.A planar phased array antenna with 265 elements is designed by using XFDTD.The co-polarized and cross-polarized component of far field is computed.The changing rule of typical phased array polarization characteristic in different beam position is obtained by spatial polarization character istic.Result shows th... |
