提出一种多重主成分分析方法, 是对原始遥感数据经过图像变换或运算处理后, 再有针对性地对专题信息进行二次乃至多次提取的图像处理方法, 同时也是对多种不同类型, 不同分辨率的遥感图像进行综合处理的尝试。应用于柴达木盆地西部山区提取地质构造信息获得显著效果。图像上新发现了一个鼻状圈闭及一组连接上、下两个断裂带的弧形纹理。

A new way of multi_principal component analysis is proposed. The image processin g technology of information re_extraction focuses on the special objects based o n the original remote sensing data being processed by some conventional methods. Meantime, it is a way to process comprehensively different remote sensing data with different spatial resolutions and spectral ranges. The application of the m ethod has shown good result for extracting geological structure information in w est Qaidam Basin of China.
