摘　　要：介绍了一种基于数理统计分析技术的铀矿蚀变信息高光谱建模技术,它利用了高光谱数据细微、丰富的光谱信息,根据岩石和蚀变的光谱特征与物质成分的关系,通过矿物中特定离子或离子基团的诊断性吸收谷的特征参数反演岩矿的物质成分,从而综合识别蚀变信息,将为航空和航天成像光谱遥感的应用开辟一个矿物蚀变信息识别和区分的研究途径。This paper introduced a hyperspectral modeling technique for uranium mineral alteration information based on mathematical statistics analysis. This technique used plenty of spectral information in hyperspectral data, according to the relationship between spectral characteristics of rock and alteration and their physical components. It can inversely calculate physical components of minerals through the spectral feature parameters of diagnostic absorption peak of special ion or ionic groups in the minerals, accordingly identify alteration information synthetically. It would provide a research method for identifying and distinguishing mineral alteration information in the application of airborne and spaceflight imaging remote sensing.
