Abstract

脉冲星历表是高精度计时的前提,也是基于脉冲星计时等应用的关键。脉冲星历表构建通常以计时模型为基础,通过对脉冲星长期高精度的计时监测和一定的数学方法估计历表中的参数来实现的。首先概要介绍了射电脉冲星计时观测步骤;然后,描述了脉冲星的计时模型和站点到达时间转换到太阳系质心的计算流程;最后,对基于最小二乘的脉冲星历表构建方法进行了较为详细的阐述。

Other Abstract

Pulsar ephemerides are basis for pulsar timing and relevant applications. Through long-term high precision timing observations, pulsar parameters are fitted via different mathematical methods to form pulsar ephemerides eventually. Firstly, the main procedures to acquire site arrival time in radio band are presented in this paper. Secondly, the timing model which is used to transform site arrival time to solar system barycenter is discussed. Finally, the traditional methods based on least square methods to fit pulsar parameters are described in detail.
