【摘要】：全月表橄榄石作为月球形成演化的指示矿物,其含量分布是月球探测研究的热点。月球卫星多光谱或高光谱数据,为利用反射光谱反演全月表橄榄石含量提供了可能。利用51组由月壤特征协会(LSCC)得出的月壤反射波谱及相应的实验室实测橄榄石含量,建立了4个反射波谱与橄榄石含量回归模型,其余6组LSCC数据作为模型验证数据。在分别解算不同模型系数的基础上,结合LSCC验证数据,比较评价不同模型标准偏差和相关系数,以及橄榄石含量分布散点图,优选出利用光谱反射率数据反演月表橄榄石含量的模型。从而利用Clementine卫星UV/VIS/NIR 5个波段的反射光谱数据反演了全月表橄榄石含量分布,通过与Apollo登月采样点实际测量橄榄石含量进行比较,验证了其结果可靠性。
[Abstract]:As an indicator of lunar formation and evolution, the content distribution of the whole moon surface olivine is a hot spot in lunar exploration. The multispectral or hyperspectral data of lunar satellite make it possible to retrieve the whole moon surface olivine content by reflection spectrum. Four regression models of reflection spectrum and olivine content were established by using 51 groups of reflection spectra of lunar soil derived from (LSCC) and the corresponding laboratory measured olivine content. The other 6 groups of LSCC data were used as model verification data. On the basis of solving the coefficients of different models and combining with the LSCC verification data, the standard deviation and correlation coefficient of different models and the scattered plot diagram of olivine content distribution are compared and evaluated. A model for retrieving the content of olivine from spectral reflectance data was selected. From the reflection spectrum data of UV/VIS/NIR of Clementine satellite, the whole moon surface olivine content distribution is inversed, and the reliability of the result is verified by comparing it with the actual measurement of olivine content at the Apollo lunar landing sampling point.
