摘要
车载遥测跟踪站天线展开后,需要进行远场标校复查。由于受标校距离、天线仰角以及周围环境等各种条件的限制,使得主天线、引导天线的光电轴匹配检查难以保证精度要求,从而影响跟踪性能。针对这些问题,本文提出在近场条件下直接悬挂信标机进行标校复查,以保证光电轴匹配精度。并针对YQ- 312 S频段遥测跟踪车载站的实际推出角度转换公式。
After the deployment of a mobile 5m S band telemetry tracking ground station,it is necessary to recalibrate whether the antenna beam axes and the lines of sight of the main antenna and the guiding antenna be parallel with each other.In fact,restrainted by the conditions of specified range field,it is difficult for the recalibration to be satisfied with the precision requirement.In this paper,a recalibration method is proposed that only a beacon transmitter should be used.The expressions of angle conversion are deduced.At the end,the exprimental results are presented.
