摘要
研究了在观测天区固定的前提下,小视场星跟踪器视场内只有两颗观测星时的星图模式识别算法。首先简述了研究的必要性;接着简要介绍了实时星图的预处理;随后详细论述了所提出算法的具体步骤;然后说明了导航星表的制定过程。仿真结果表明了算法是有效的,并对仿真试验结果进行了分析;最后给出了结论。
The two-star pattern recognition method is researched on the small field of view provided that the sky-area to be observed is fixed. Firstly,the need is stated briefly.Then the pretreatment of the real-time star pattern is presented in short. Subsequently the pattern recognition algorithm used in the article is discussed in detail.And then the process to build the reference star catalog is explained.The simulation shows the algorithm is effective. The result is analyzed. Finally the conclusion is presented.
