下压段作为助推滑翔高超声速导弹的导引段,其攻击范围直接决定导弹可执行的使命任务以及可打击的典型目标。基于三自由度下压段弹道仿真模型和满足落角约束的最优导引律模型,建立下压段起始高度等因素对导弹攻击范围的影响分析模型,并通过弹道平移的方法仿真分析各因素对攻击范围的影响。通过仿真分析得出各影响因素对助推滑翔高超声速导弹攻击范围的作用机理,可为导弹下压段弹道设计及导弹作战能力评估提供理论和技术支撑。

As the guidance part of the boost glide hypersonic missile, dive phase attack range directly determines the mission and typical target of the missile. Based on the three degree of freedom trajectory simulation model of the dive phase and an optimal guidance law model satisfying the fall angle constraint, an analysis model of the impact of some factors, such as the dive phase starting height on the boost glide hypersonic missile attack range is established, and the impact of various factors on the missile attack range is analyzed by trajectory translation method. Through simulation analysis, the influence of various factors on the missile attack range is obtained, and it will provide theoretical and methodological guidance for trajectory design of the dive phase and operational capability assessment.
