| 摘要: |
| 主要研究空间预警系统利用星载红外传感器的视线测量估计弹道导弹自由飞行段弹道的问题。针对目标运动的弱可观测性，提出了位置与速度依次滤波的改进Gauss-Newton方法，解决了自由段弹道的最大似然估计问题，利用Monte Carlo仿真实验验证了估计方法的有效性，并对估计误差进行了分析。 |

| Abstract: |
| By using the line of sight (LOS) measurements from space-based infrared sensors, free flight phase trajectory estimation problem of ballistic missile is studied. Taking into account poor target motion observability, maximum likelihood estimation problem of trajectory is solved by using an improved Gauss-Newton algorithm by which the position and velocity are filtered in turn. Monte Carlo stimulation verifies the efficiency of this algorithm. Besides estimation error is analyzed. |
