Ionospheric Refraction Correction in Radio Astronomy
-
摘要: 本文利用极坐标下斯涅尔定律,系统地讨论了电离层折射对赤经赤纬的修正问题,并据此给出了射线描迹法。结合北京地区电离层探测资料,对电离层折射造成的赤经赤纬的修正进行了理论估算,得到了一些有意义的结论。Abstract: Using the Snell’s law in polar coordinates, the ionospheric refraction effects on the declination and right ascension determination is discussed in this paper. A ray tracing method is also given. With the ionospheric data observed in Beijing, the correction of ionospheric refraction is estimated and some usefull conclusions are drawn.
