河外射电源地面VLBI观测的相对论时延模型

Ground-based VLBI Relativistic Time Delay Model for Extra-Galactic Source

  • 摘要: 重新研究了河外射电源地面VLBI观测的相对论时间延迟模型1,2,给出了一个严格解析的表达式。根据公式可以得到数据处理中常用的Zhu Groten模型、Shapiro模型和IERS推荐模型3,4,详细地给出了时间延迟理论模型的计算步骤,介绍了各种时间系统的转换和使用方法。

     

    Abstract: A rigorous analyzed expression is presented,from which a couple of models commonly used in VLBI data-processing can be easily deduced.Computation steps are given in detail.The various time systems and their relationship in this model are introduced.
