| 摘 要： | 采用广义Ｋａｌｍａｎ滤波方法，通过在北天东雷达直角坐标系内建立相应的再入目标状态及雷达观测方程，再入目标的机动特性用一阶高斯马尔科夫过程描述，并增广到状态方程组之中，根据获得的带有测量误差的雷达测量信息对再入机动目标弹道进行估计，得到了满意的结果。

| Abstract: | In this paper,the state and radar measurement equations of reentry maneuvering target are established in the north zenith east coordinate system The maneuvering model of target is described by a Gauss Markov process and augmented into the state equations Then,on the basis of all above,the kalman filter is used to estimate the trajectory of the reentry maneuvering target in terms of the radar measurement information influenced by errors The simulation results show the effectivity of the method |
