| 摘 要： | 针对弹道导弹星象跟踪实时性问题,提出星象跟踪的实时性改进的一种新方法。该方法根据星象跟踪/预测方法与跟踪模式特点,首先,建立了基于统一存储的星表模式库,并采用k-vector作为检索方法,以提高检索速度;其次,为实时生成局域星象信息集合,提出了并行多维检索的方法,以节省提取星像信息的时间;最后,进行算法性能分析。仿真实验结果表明:该算法能够大大地提高星象跟踪的实时性,提高导弹命中精度。

| Abstract: | Aiming at the real-time star tracking problem of missile,a new method for real-time star tracking is proposed.According to the characteristics of star tracking/predicting and tracking mode,firstly,star model catalog based on unified storage is established,and k-vector is used as searching method to improve searching speed;Secondly,in order to real-time generate information set of local star,a parallel multi-dimensional searching method is proposed to save the time of extracting the star image information;Finally,the performance of algorithm is analyzed.Simulation results show that the arithmetic can greatly improve the real-time performance of star tracking,and improve missile precision. |
