机动式飞行器具有特殊的再入机动飞行弹道。为满足空间目标跟踪的需要，研究了一种雷达测量数据处理方法。建立了能够描述目标机动段飞行状态的弹道动力学模型，分别给出了目标跟踪系统状态方程、雷达量测方程和扩展卡尔曼滤波（ EKF）方法。对飞行器机动段弹道方案数据进行仿真计算，结果表明，该跟踪算法对再入机动目标的滤波性能优异，同时可以获取空气动力参数的近似估计。

Boost?glide reentry vehicle has a special maneuvering trajectory.A radar tracking data processing method is studied for the measurement of the reentry target.Firstly,the trajectory dynamic model that can describe the maneuvering state of the target during the phase of gliding flight is established,and then the state equation for the target tracking system,the radar measurement equation,and the extended Kalman filter (EKF) processing are presented.Finally,the computer simulation is performed using the glide trajectory datum of a vehicle.The results indicate that the filtering performance of the tracking algorithm is excellent for the reentry maneuvering target and the aerodynamic parameters can be approximately estimated.
