【Abstract】 The unscented kalman filter( UKF) is firstly used to estimate the trajectory of reentry targets in virtue of spacecrafts’ dynamic models,and then the result with the solution of traditional 3RR method is compared. The simulation result shows that UKF based on the dynamical model can effectively improve the estimation precision of reentry targets’ trajectory.更多还原
