摘　　要：遥感影像数据的光谱信息分析与处理是目前遥感应用的热点之一。通过多年的遥感教学实践,依据PHI(Pushbroom Hyperspectral Imager)航空高光谱影像像元光谱维矢量数据,总结了基于EXCEL软件的高光谱影像地物光谱构建、光谱特征及其相关性分析、光谱微分计算、光谱向量相似性度量等光谱分析与信息识别的教学方法,以使学生在学习专业知识过程中增加实际工作经验与科研能力。Spectral information analysis and processing were emphasized particularly on spectral dimension of remote sensing imagery. The EXCEL software package can be used in hyperspectral analysis such as restructuring of feature spectra, spectral derivatives, correlation analysis between features, likelihood measurement among spectral vectors, and information extraction using spectral reflectance features. Based on years＇ teaching practices and the airborne Pushbroom hyperspectral imager（PHI） hyperspectral imagery, the approaches could be applied to research-type teaching, and would help effectively college students to enhance their practical experience and research abilities.
