| 摘 要： | 在对空间非合作目标天基测角卡尔曼滤波定轨中,目标机动会导致常规卡尔曼滤波器发散.提出一种无迹卡尔曼滤波(UKF)结合带次优渐消因子的无迹卡尔曼滤波(SFUKF)的滤波定轨方法,目标无机动时使用UKF,在目标机动时使用SFUKF,给出了目标机动的判断准则.仿真结果表明,此滤波方法在目标无机动时有较高的状态估计精度,在目标...

| Abstract: | During the determination of the orbit of a non-cooperative target in space by using Kalman filter,the maneuver of target can cause the divergence of conventional Kalman filter.In this paper,an orbit determination method of using UKF and SFUKF is developed.The UKF is used when the target has no maneuver,and the SFUKF is used when the target maneuvers.The law of recognizing the maneuver of the target is given.The mathematics simulation results show that the new filter can track the maneuvering target,and the ... |
