摘　　要：文中对再入弹道目标的质阻比估计算法进行了讨论;分析了解析法计算目标质阻比的主要影响因素,同时讨论了实时估计质阻比的算法。在考虑再入目标质阻比的时变特性前提下,仿真了地心坐标系下再入弹道目标的二维轨迹;最后用该仿真轨迹数据对实时质阻比估计算法进行了验证分析。Estimation algorithm of mass-to-drag of ballistic reentry vehicle is discussed in this paper. Significant contributions when calculating the mass-to-drag by using analytical formula are analyzed; Real-time estimation process of mass-to-drag based on ana- lytical formula is studied based on the above analysis. By taking account of the time variant prosperity of the mass-to-drag, two di- mensional trajectory of ballistic reentry vehicle is simulated. Finally simulation results demonstrate the validity of the real-time estimation algorithm.
