X射线脉冲星导航探测器研究进展

Research Progress of X-Ray Pulsar Navigation Detector

X射线脉冲星导航作为新兴的航天器自主导航技术,具有抗干扰能力强、自主性强、导航误差小等优势,被多个国家规划为重要的发展项目。脉冲星探测存在X射线辐射流量微弱、空间本底噪声大、X射线易散射等问题,因此高灵敏度、高精度的X射线探测器系统的研制具有极其重要的意义。本文介绍了X射线脉冲星导航的基本流程和X射线脉冲星探测的发展历程,重点介绍了几种常用X射线探测器和X射线探测器系统,并对X射线探测技术的未来发展进行了展望。

As an emerging autonomous navigation technology for spacecraft, X-ray pulsar navigation has the advantages of strong anti-interference ability, strong autonomy and small navigation error, and has been planned as an important development project by many countries. There are some problems in Pulsar detection, such as weak X-ray radiation flow, large space background noise, and easy scattering of X-rays. Therefore, the development of a high-sensitivity and high-precision X-ray detector system is of great significance. In this paper, the basic process of X-ray pulsar navigation and the development of X-ray pulsar detection are introduced, with emphasis on several commonly used X-ray detectors and X-ray detector systems, and the future development of X-ray detection technology is prospected.
