摘要
为克服过顶限制,发展出X-Y天线座应用于航空器和低轨卫星的全半球跟踪。文中分析了影响X-Y天线座轴系精度的一些主要因素,分类作了介绍,并与方位-俯仰型天线座进行了对比。可为X-Y天线座轴系设计提供参考。
To overcome zenith-passing limitation, an X-Y pedestal architecture has been developed to track aircraft and LEO satellites over the entire hemisphere. This paper analyzes some main factors that affect precision of axis system of X-Y pedestal, classifies these factors and compares the X-Y pedestal with the A-Z pedestal. It can be used as reference for the design of axis system of pedestal.
