摘　　要：基于飞行器再入段的动力学模型,利用UKF对目标的弹道进行估计,并与传统的3RR法解算结果进行了比对。仿真结果表明,基于动力学方程的UKF法可有效地提高弹道式再入目标弹道的估计精度。The unscented kalman filter（UKF） is firstly used to estimate the trajectory of reentry tar- gets 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
