Guide star selection method applied to ballistic missile

  • 摘要: 针对当前适用于弹道导弹的导航星选取方法较少,研究了一种根据标准弹道均匀化选取导航星的方法.通过分析导弹飞行弹道及飞行参数的影响,在构建"伪天球"坐标系的基础上,确定了导航星的选取区域,简化了因射向变化、坐标越界等造成计算和搜索比较复杂的问题;基于天球上的基准点及提出的"距离-星等"加权法,均匀化地筛选导航星,并按照k-vector索引方式构建适用性较好的弹载导航星表,可以有效地提高星图识别算法的效率.仿真结果表明,该方法简单易行,选取的导航星数量少,分布均匀性好,在不降低星图识别成功率的基础上,能够有效地减少识别时间.
