摘要

摘要: 针对X射线脉冲星导航(XPNAV)系统的选星问题，该文研究了脉冲星可见性、品质因子及空间分布对脉冲星优选的影响。分别建立了第三体阴影遮挡，X射线干扰源影响以及X射线探测器视场角限制造成脉冲星不可见的约束方程；分析了基于克拉美罗界的脉冲星品质因子评价公式；提出了脉冲星组合加权几何精度因子(WDOP)的计算方法，并证明了加权几何精度因子值随着脉冲星观测数量的增加而减小。最后设计了一种基于查表法的脉冲星选星方法。仿真结果表明，设计的脉冲星选星方法可以有效地从适合导航的脉冲星中优选出最佳脉冲星组合。

Abstract: In order to select the optimal pulsars combination for X-ray Pulsar NAVigation (XPNAV), the influence factors of visibility, quality and space distribution of pulsars are studied. Besides, constraint equations for visibility based on the restrictions of celestial bodys shadow, X-ray disturbance source and detectors angle of view are built respectively; an evaluation equation for quality factor based on Cramer-Rao low bound is analyzed; the method for calculating Weighted Dilution Of Precision (WDOP), which decreases as the number of observable pulsars increases, is researched. Finally, a method for selecting pulsars based on looking up table is proposed, and its validity is proved by computer simulations.
