摘    要:论述了星敏感器捷联在弹体上,采用星图匹配技术修正导弹初始定位、定向的原理。提出了一种适用于星光制导的凸多边形算法,简化了弹载星表。由星敏感器视场中的星图,可生成唯一的最大凸多边形,基于凸多边形的星图识别算法可同时获得多颗星的瞬时位置,由此可获得弹体在赤道惯性系和发射点惯性系中的姿态及其关系。最后导出导弹初始定位、定向误差的数学表达式。仿真结果表明该方法的有效性。

关 键 词:制导  星敏感器  星图匹配  定位定向误差  凸多边形

Abstract:The principle of star patterns matching for celestial guidance to correct the initial localization and orientation errors occurred in mobile launching of ballistic missile is described. The star pattern identification algorithm based on convex polygon with star magnitudes-independent is adopted to obtain multi-stars positions. Those stars are used to calculate the attitude of missile in the celestial reference frame (CRF). The attitude of missile in the launch inertial coordinate frame (LICF) is obtained by the relation between CRF and LICF. The initial localization and orientation errors are formulated by coordinate transformation. Simulation results show the method is valid.
Keywords:celestial guidance  star sensor  star pattern matching  initial localization and orientation errors  convex polygon
