摘要： 建立了一种新的电波折射修正算法———经验 分层电波折射修正算法。经过与电波折射误差的经验修正和分层实测指数修正方法修正效果的比较 ,证实了该算法效果接近分层实测指数修正方法 ,明显优于经验修正方法。该方法为一些不具备提供分层电波折射参数的航天测控站电波折射误差修正问题 ,提供了行之有效的技术手段 ,对航天测控工程具有应用价值

Abstract: A new algorithm is built for correcting refractive error of radar signals, which is called the empirical layered correction in this paper Based on comparing with the empirical correction and the layered correction, it can be found that this new with the highest precision This new algorithm can be used in case that there are no weather stating exists to measure refractive parameters of atmosphere and can improve the precision of measurement and control of spacecraft
