| 摘 要： | 对一部待测、待评估的天线,其交叉极化特性实际上是依赖于极化基的,极化基匹配或失配情况下,得到的交叉极化性能评估结果也不一样.文中首先建立了天线极化特性测最模型,推导了交叉极化测量校准约束模型,给出了该约束下的最佳收发极化基.并针对实际的雷达天线进行了外场测量实验,实测处理结果验证了上述结论.利用约束模型可对实测的极化方向图实现有效的校准.

| Abstract: | For an antenna under tested,the polarization property is depending on the foundation of polarization basis.The polarization property will be different when the polarization basis being match or mismatch.The antenna polarization property measurement model is founded in this paper.The constrained condition model of cross polarization calibration is derivated and the optimal transceiving polarization basis is given.A real radar antenna is measured by out field test.The test results are validated with those theoretic analysis.The real antenna polarization pattern can be calibrated effectively by the proposed method. |
