摘要
一般雷达或卫星地面天线的工作范围只要求一定的扇形区域,但是对于具有特殊用途的地面天线系统,不仅要求跟踪接收信息的时间尽可能地长,而且飞行器经过天顶时,离地面站的距离最近、信号最强,所以常常提出具有过顶跟踪能力的特殊要求。文中主要针对天线的过顶跟踪问题进行了分析,并结合三轴天线座在机械方面对过顶跟踪问题的解决进行阐述。在工程实践中已经得到验证。
The operation range of normal radar and satellite earth station require a certain fan - shaped sector only. But there are more requirements to the earth station antenna for special application. Not only is the time for down-link tracking required but also require the zenith-passing function, because the signal is strongest in this sector. In this paper, the problem of vertex tracking for the antenna was analyzed, and combined with three-axis antenna pedestal in terms of the mechanical solution to the problem of vertex tracking was discribed. In engineering practice has been verified.
