| 摘 要： | 针对空间信息对抗中的侦察卫星变轨和对地面“静默”等特点，本文提出了一种基于UT(Unscented Transform)变换的UKF(Unscented Kalman Filtering)滤波跟踪方法，实现了单个侦察卫星仅仅测量角度对辐射卫星的轨道的无源跟踪和定位，经过计算饥仿真表明，仅仪利用单个卫星对卫星只测角定位是可能的，且在测角精度较高时，该方法的轨道跟踪精度可达1公里以内。

| Abstract: | To the features such as dogleg and silence of reconnaissance satellite in space counter measures,a tracking algorithm,called Unscented Kalman Filtering(UKF),which based on Unscented Transform(UT) is put forward.It trealizes passive tracking and locating the orbit of satellite by bearings.Computer simulation indicated that it is possible to track satellite by single satellite using bearings-only measurement.Tracking error of orbit position could be less than 1 Km when the precision of bearings measurement is high. |
