摘要
针对传统的S频段统一载波测控通信系统自动校相方法不能满足日益加重的长管任务,提出了一种新的校相算法,并给出了实现该算法自动化的具体方案。理论分析和实验结果表明,利用该方法进行定向灵敏度标校减小了系统交叉耦和值。自动化的实现节约了人工操作的时间,因此该方法具有速度快、精度高的优点。精度高大大改善了地面测控系统的跟踪性能;速度快缩短了战前标校时间,为任务前地面测控系统快速切换到任务状态赢得了更多的宝贵时间。
Since traditonal auto phase calibration method for S Band unified TT&C system can't satisfy the increasing requirements of long administration mission, this paper presents a new auto phase calibration algorithm and it' s automatic implementation scheme. Theoretical analysis and test results demonstrate the new algorithm decreases the value of cross coupling when used in directional sensitivity calibration. The realization of automatization saves so much time for manual operation, that the algorithm has the advantages of fast calibration and high accuracy. With the high accuracy and fast calibration the new algorithm grleatly improves the earth station TT&C system tracking performance and decreases the calibration time that can save a lot of time for switching to the mission state.
