MIDAS_IV系统中跑道视程RVR算法分析

摘要

介绍了气象能见度、气象光学视程MOR及跑道视程RVR的由来以及它们之间的相互关系，对如何计算MIDAS_IV系统中的跑道视程RVR进行了深入分析和实例解释。%This paper introduces the origin of meteorological visibility, meteorological optical range （MOR） and runway visual range （RVR） as well as their relationship among them. Then, how to calculate RVR in MIDAS_IV system is analysed and practical interpreted.
