| 摘 要： | 动态电轴跟踪系统是常用的雷达罩电性能测试系统,该系统在使用过程中存在着被测天线扭极化的问题。对造成扭极化的原因进行了分析,确认该问题是由雷达罩转台和天线转台方位轴不同轴造成的。利用几何光学三维射线跟踪法对扭极化的危害进行了分析。提出了扭极化问题的解决方案,即将天线转台安装到随动于雷达罩方位轴的天线支杆上。同时归纳出了动态电轴跟踪系统中被测天线的安装要求。

| Abstract: | Dynamic boresight tracing system is usually adopted for the radome electrical performance test.This system has antenna torque polarization problem when it is put into application.The cause of the torque polarization which is the azimuth axes inconsistence between the radome positioner and the antenna positioner is analyzed and concluded.In further,the detriment of torque polarization is analyzed.A solution for this problem is proposed according to a method of geometrical optics three dimensional ray tracing,that is,installing the antenna positioner on the antenna prop stand of the radome azimuth axes.In conclusion,the installing requirements of tested antenna in the dynamic boresight tracing system are given. |
