中低轨红外预警弹道估计及精度分析

Trajectory Estimate and Precision Analysis under the Early Warning of Medium or Low Orbit Satellite

解决了在一颗中低轨预警卫星的条件下的导弹定位和弹道估计问题,主要以自由段弹道方程式为模板,与观测数据作匹配得到导弹初始观测点参数,确定整个弹道.通过精度分析和仿真实验,证明方法的有效性和可行性.

The missile positioning and ballistic estimate were resolved under the conditions of a single medium or low orbit satellite for infrared early warning. Based on the trajectory formule of free flight period and matched with observation value, the first detected point parameters of missile were obtained, and the total trajectory was also obtained. The presision analysis and simulation test show that the method is effective and feasible.
