摘要: 脉冲星导航试验卫星是我国发射的一颗专用试验卫星.经过4个多月的在轨观测,该卫星已成功获取了大量观测数据.介绍利用该卫星搭载的掠入射聚焦型X射线探测器在近4个月中对PSR B0531+21获得的观测数据第一批处理结果.本文详细阐述掠入射聚焦型X射线探测器的观测模式,给出脉冲星观测数据的处理方法以及脉冲星参数的拟合过程,利用基于第一手观测数据的脉冲星精化参数验证掠入射聚焦型探测器在轨工作性能,得以回答使用国产X射线探测器是否能够“看得见”脉冲星问题.

Abstract: Xray pulsar navigation test satellite is a dedicated test satellite developed by China. This satellite has obtained a great mount of science data during the flight of more than 4 months. In this paper, the first analysis result of science data that was collected by the focusing Xray detector carried by the satellite in recently 4 months. The observation mode of this detector is introduced, the method of the science data analysis as well as the pulsar parameters correction are provided, the refined pulsar parameters are estimated, the performance of the detector in orbit is tested, and the question whether homemade Xray detector is able to detect the pulsars is answered.

Key words: flight test, data analysis, Xray detector, profile folding
