| 摘 要： | 本文通过对电离层形态结构的分析以及建立适当的模型来讨论电离层折射对干涉仪输出的影响,并提出了改正方案。在讨论过程中,作者考虑了层下点在赤纬方向的运动,并提出了一种把电离层预报值与实测值结合起来修正层下点处f0F2的方案。这些工作虽然是针对密云米波系统的,但这些方法中的某些考虑可以推广到一般的电离层折射误差改正中去。

| Abstract: | The influence of ionospheric refraction on the output of interferometer is discussed and the method used to correct it is suggested. In the discussion the motion of sub-ionospheric point along the direction of declination is considered, and a new method to modify the value of f0F2 at sub-ionospheric point is proposed. Although these methods presented here are for correcting the ionospheric refraction of Miyun System, yet some ideas of these methods can be used in other cases. |
