摘　　要：分析了双星观测视线与弹道导弹主动段实际位置的关系,针对传统弹道导弹主动段状态估计算法中卫星观测角度值解耦难题,提出了基于导弹位置估计点与卫星观测视线距离的双星观测弹道导弹主动段状态最优估计方法,将红外卫星的观测角度二维信息融合为一维距离信息,避免了方位角及俯仰角耦合问题对最优估计算法的影响,保证能够得到高精度的状态估计,最后通过仿真实验验证了算法的有效性及准确性.The relation between lines of sight（LOS） of two satellites and location of ballistic missile in boost phase is analyzed.Based on the distance of estimation location to the LOS,a new algorithm is given out to resolve the problem of dismissing the relation of observation angles＇ value in former optimal estimation algorithms.With this algorithm,two-dimensional information of observation angles is fused into one-dimensional information,and the influence of coupling observation angles＇ value to optimal estimation algorithm is removed.This method ensures high state estimation precision.Finally,the results of theoretic analysis are validated by Monte-Carlo simulations.
