基于单星焦平面模板的弹道匹配研究

Matching of Ballistic Missile Trajectory Based on Single Satellite Focal Plane Template

针对弹道导弹预警跟踪中存在的获取的目标信息不完整、数据率低的问题,给出了一种基于单星焦平面模板的弹道匹配方法,方法直接对焦平面图像中目标点所在像元的位置数据而非传统的角度数据进行灰色关联分析,同时规避了传统方法中必需的射向估计。仿真结果表明,模型能够准确的匹配出目标弹道并对落点做出较为准确的预测,具有很强的理论及实际意义。

Concerning the problem of incomplete information and limited data exist in ballistic missile warning and tracking,a method of matching ballistic missile trajectory based on single satellite focal plane template was put forward. This method analyses the position data of a target on the focal plane rather than the angle data and slides over the course head estimation in traditional method. The right template is picked out and the exact impact point is estimated in the simulation which shows the significance of the method in theory and practice.
