Photometric Analysis of Lunar Regolith Based on the Bidirectional Reflectance Data of Apollo Samples

了解不同观测角度下的月壤光散射特征, 不仅可以为月表光谱数据的光度校正或解混提供参考依据, 还可以帮助解译月壤物质的化学特性或物理性质. Hapke模型被广泛地应用于月表光度学分析中, 但不同研究中所选取的模型参数组合不同, 导致得到的月壤光度参数存在差异, 无法进行直接的对比分析. 为了更好地理解月壤光度特性, 基于6个不同Apollo月壤样品的二向反射测量数据, 选用不同参数组合的Hapke模型进行光度学分析, 获取了月海和高地月壤的光度参数. 同时, 对比了二项勒让德形式相函数与Henyey-Greenstein相函数, 以及3参数与5参数Hapke模型在月壤光度学分析中的适用性. 分析结果可为月壤光谱数据处理过程中的模型选择与后续解译提供参考.

Abstract

了解不同观测角度下的月壤光散射特征, 不仅可以为月表光谱数据的光度校正或解混提供参考依据, 还可以帮助解译月壤物质的化学特性或物理性质. Hapke模型被广泛地应用于月表光度学分析中, 但不同研究中所选取的模型参数组合不同, 导致得到的月壤光度参数存在差异, 无法进行直接的对比分析. 为了更好地理解月壤光度特性, 基于6个不同Apollo月壤样品的二向反射测量数据, 选用不同参数组合的Hapke模型进行光度学分析, 获取了月海和高地月壤的光度参数. 同时, 对比了二项勒让德形式相函数与Henyey-Greenstein相函数, 以及3参数与5参数Hapke模型在月壤光度学分析中的适用性. 分析结果可为月壤光谱数据处理过程中的模型选择与后续解译提供参考.
