摘要
简要概述了GNSS掩星探测大气的发展历史与国内外的研究现状;详细叙述了无线电掩星反演大气参数的基本原理,主要包括几何光学下的相位反演,中性大气层、电离层、振幅的反演,分辨率的定义以及无线电掩星技术系统与标准算法和误差分析;并针对该技术的一些特点,指出了若干尚需深入解决的问题;最后展望无线电掩星观测技术在数值天气预报(NWP)等领域的发展。
After introducing the development of GNSS occultation measurements of the atmosphere, the paper discusses the basic fundamental of the inversion menthods of retrieving atmospheric profiles with GNSS radio occultation measurements. Considering its characteristic, the paper points out several technical problems which need to be resolved further.
