摘要
首先总结了比值法、主成分分析法、光谱角法和混合调谐滤波法等研究方法,然后利用这些方法分析了ASTER数据,对西藏雄村斑岩铜金矿进行了研究,并对比了各种方法的研究效果。结果表明,主成分分析法与光谱角法效果最好。
At first,we summarized the previous methods,such as band batio,principal component analysis,spectral angle mapper and mixture-tuned matched-filtering in this article.And then we studied the Tibet Xiongcun porphyry copper-gold deposit by analyzing ASTER data.Finally we compared the results of different methods used in the district.The results show that the principal component analysis and spectral angle mapper are the best.
