标题： Measurement of X-ray Photon Energy and Arrival Time Using a Silicon Drift Detector

摘要： 探测脉冲星的X射线辐射以及获取光子到达时间是基于X射线脉冲星测量的自主导航的基础步骤。脉冲到达时间的精度主要由光子到达时间的精度决定。在这项工作中，使用硅漂移探测器来测量光子的能量和到达时间。该测量系统包括一个信号探测器、一个处理单元、一个信号采集单元和一个数据接收单元。该系统获取光子的能量分辨率和到达时间信息。特别是，当具有不同能量的背景噪声干扰折叠周期时，该系统能够获得高信噪比的脉冲轮廓。地面测试结果表明，该系统可以应用于以X射线脉冲星测量作为有效载荷的自主导航。 显示英文摘要

摘要： Detecting the X-ray radialization of pulsars and obtaining the photons' time of arrival are the foundation steps in autonomous navigation via X-ray pulsar measurement. The precision of a pulse' s time of arrival is mainly decided by the precision of photon arrival time. In this work, a silicon drift detector is used to measure photon energy and arrival time. The measurement system consists of a signal detector, a processing unit, a signal acquisition unit, and a data receiving unit. This system acquires the energy resolution and arrival time information of photons. In particular, when background noise with different energies disturbs epoch folding, the system can acquire a high signal-to-noise ratio pulse profile. Ground test results show that this system can be applied in autonomous navigation using X-ray pulsar measurement as payload.
