摘　　要：为实现空间目标监视雷达状态的实时监测,提出了一种基于轨道理论的空间目标监视雷达状态实时核验方法.首先基于轨道理论实时计算空间目标每一跟踪弧段的量测值与理论计算值之间的偏差,根据偏差从数据级判断雷达工作状态以及数据质量;然后准实时利用精密星历和雷达量测定量分析雷达跟踪精度.实验分析表明,该方法通过实时和准实时结合,可有效提升数据整合和开发利用能力,为空间作战任务的决策提供数据支持的能力.In order to achieve the real-time status monitoring of space target surveillance radar,this paper proposes a real-time verification method for space target surveillance radar status based on the orbit theory.Firstly,based on the orbit theory,the paper calculates in real time the deviation between the measured value and the theoretical calculated value of each tracking arc segment of the space target,judging the radar working status and data quality from the data level according to the deviation,and then in quasi-real time uses the precision ephemeris and radar measurement to quantitatively analyze the radar tracking accuracy.Experimental analysis shows that through the combination of real time and quasi-real time,the proposed method can effectively improve the capabilities of data integration,development and utilization,as well as the capability to provide data support for decision-making in space combat missions.
