【摘要】:全月表橄欖石作為月球形成演化的指示礦物,其含量分布是月球探測研究的熱點(diǎn)。月球衛(wèi)星多光譜或高光譜數(shù)據(jù),為利用反射光譜反演全月表橄欖石含量提供了可能。利用51組由月壤特征協(xié)會(LSCC)得出的月壤反射波譜及相應(yīng)的實(shí)驗(yàn)室實(shí)測橄欖石含量,建立了4個反射波譜與橄欖石含量回歸模型,其余6組LSCC數(shù)據(jù)作為模型驗(yàn)證數(shù)據(jù)。在分別解算不同模型系數(shù)的基礎(chǔ)上,結(jié)合LSCC驗(yàn)證數(shù)據(jù),比較評價不同模型標(biāo)準(zhǔn)偏差和相關(guān)系數(shù),以及橄欖石含量分布散點(diǎn)圖,優(yōu)選出利用光譜反射率數(shù)據(jù)反演月表橄欖石含量的模型。從而利用Clementine衛(wèi)星UV/VIS/NIR 5個波段的反射光譜數(shù)據(jù)反演了全月表橄欖石含量分布,通過與Apollo登月采樣點(diǎn)實(shí)際測量橄欖石含量進(jìn)行比較,驗(yàn)證了其結(jié)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.
