摘　　要：为了在单星探测预警情况下及早地给出弹道导弹的射向估计,有效引导地基雷达进行接力跟踪,在不考虑弹道模板先验信息的情况下,从导弹的动力学模型出发,利用带有区间约束的LMF算法,建立了基于单星观测的弹道导弹射向估计算法.相应的仿真算例表明,该方法对于引导而言,达到了较高的估计精度,具有实用价值,为天基预警系统弹道导弹早期预警提供了一种可行的求解方法.In order to early estimate the course head of ballistic missile by single-satellite so as to lead the ground-base radar effectively,the course head estimation method based on missile dynamic equations was proposed.While establishing the estimation method,the prior information of ballistic template was not considered,and the LMF algorithm with zone restricted was applied.The corresponding simulation shows that the method possesses high estimation precision with regard to guidance,and it is practical,and it o...
