Mineral target detection using the spaceborne hyperspectral images do not leads to accurate results because of the low spatial resolution. Therefore it might be better to use images with much more spatial resolutions in order to achieve good results. However, although airborne hyperspectral images have moderately good spatial resolutions but they are too much costly. Consequently it would be great if we could find a solution for the mentioned problem in low cost satellite images (such as Hyperion). In this study, a process was proposed to apply an intermediate spectrum from Hymap airborne image, to detect some minerals in the spaceborne Hyperion image. The study was conducted in east Iran and it was carried out on four mineral targets including: Kaolinite, Alunite, Epidote and Hematite. Experimental results indicate that the performance was better in intermediate spectrum for entire minerals, by 4.47, 11.38, 4.32 and 10.28 percent respectively in Alunite, Kaolinite, Epidote and Hematite.  

Keywords: Target Detection, Intermediate Spectrum, Hyperspectral Images, Minerals, Spectral Feature Fitting algorithm.
