摘要
在室外测试场,影响超短波天线增益测试精度的因素很多,地面二径反射波是最主要的误差来源。为消除其对天线增益测量带来的误差,引入二径干涉损耗对天线增益进行修正,提高了天线增益测量精度。
There are many factors affecting the VHF antenna gain test accuracy in the outdoor antenna test site. Ground reflected wave is the most important source of error. To eliminate the measurement error , this paper propose the two-path interference loss to modify the antenna gain,which improved the antenna gain accuracy.
