【摘要】 我国开展的火星探测萤火计划(YH-1)的研究中,用地基掩星观测反演火星大气是其中一个重要的组成部分。由于各种观测资料处于日心和火星坐标系中,不易利用和处理。本文通过矩阵变换建立掩星坐标系,把原始的观测资料统一到同一个坐标系中,为掩星数据的分析处理提供了技术准备。更多还原

【Abstract】 Chinese Mars exploration program YingHuo(YH-1) is processed.Ground-based occultation observation of the Martian atmosphere is an important part of this program.The observation data,coming from heliocentric system and Mars coordinate system respectively,is uneasy to use and to process.Martian occultation-plane coordinate system is set up by matrix transformation,and the original observation data is converted into this coordinate system,ready for inversion data analysis.更多还原
