摘　　要：针对雷达测量跟踪有轨道机动的非合作航天器的定位和轨道计算问题,在EKF的基础上引入强跟踪滤波器,采用增广的航天器轨道动力学模型,估计推力加速度。在航天器进行轨道机动时,滤波器自身可完成对轨道机动的快速判断和检测,滤波过程无需额外的检测手段,通用性高,可适用于针对非合作空间目标的轨道计算和跟踪与定位。数值仿真表明,对雷达数据,轨道机动约10 s后即可检测出发生了轨道机,位置精度在几十m量级,速度精度在0.1 m/s量级。A strong tracking filter based on EKF and UKF is used for orbit calculating during spacecraft orbit maneuvers using radar non-cooperative spacecraft measurement. The filter can detect the orbit maneuver quickly without additional detecting means. It is suitable for orbit calculating, tracking and positioning of non-cooperative spacecraft. The numerical simulation shows that by using radar measurement, the orbit maneuver can be detected after 10 s. The position accuracy is on the order of tens of meters, and the velocity accuracy is on the order of 0.1 m/s.
