Research on detectors in X-ray pulsars-based navigation system

综述了基于X射线脉冲星导航系统探测器的原理,分析了现有的几种不同类型探测器的性能、测时特点和应用的局限性;给出了由多只探测器组成的探测器系统的原理设计,并分析了探测器系统的构成、安装方式以及处理电路;阐述了X射线脉冲星导航系统探测器在航天器导航中的应用以及国外应用先例,为基于X射线脉冲星导航系统探测器的研制提供有用的参考。

A survey is given on the principles of detectors used in the X-ray pulsars-based navigation system. And analyses of the existing detectors are presented, about the detectors＇ performance, timing characteristics, and their limitation within application. After each individual detector is described, the principle of detector system composed of multiple detectors is designed, and the components, the manner of fixing, and the processing circuit of the detector system are analyzed. The application of detectors in spacecraft navigation, especially the prior use in the USA ,is described ,which provides useful reference for the research and development of detectors used in the X-ray pulsars-based navigation system.
