摘　　要：研究了面向星敏感器的星模式识别算法。首先扼要介绍了到目前为止出现的所有面向星敏感器的星模式识别算法和星图预处理,然后详细论述了本文提出的基于旋转和比例不变点特征松弛匹配算法的一种新的面向星敏感器的星模式识别算法。在第三部分通过仿真试验检验了新算法的性能。初步的仿真试验结果表明该星模式识别算法性能优良,具有实用价值。最后讨论了待深入研究的问题。In the article the star-pattern recognition algorithms for a star tracker are studied. At first all star-pattern recognition algorithms that appeared before and the star-image pretreatment are introduced. Then a new star pattern recognition algorithm for a star tracker, based on point pattern relaxation matching method which is rotation - and - scale invariant, was discussed in detail. In the third part, its performance was checked up by some simulation experiments. The primary results indicate the star pattern recognition algorithm has good performance and utility value. At last some questions to be investigated in future are discussed.
