摘　　要：红外多光谱扫描仪（IRMSS）是中巴地球资源卫星（CBERS）上的重要有效载荷之一。其获取的红外图像可以在国民经济的各个领域得到广泛应用。但是由数传系统传回的图像数据不能直接用,必须经过相应的处理。文章介绍的内容就是如何设计一个处理系统,将这种不可直接用数据经过解码和图像格式的处理,得到可视图像;经过图像预处理,得到零级图像;经过相应的辐射校正处理,得到一级图像:经过几何校正处理,得到二级图像产品,提供给其它经济各部门加以应用。The infrared multi - spectral scanner (IRMSS) is an important component of the China Brazil earth resource satellite(CBERS - l) .The application of its image is very wide in the departments of country. Because the image data from data transmission can not be used directly, we should carry out some processing. In this paper, we introduce an technology to deal with this problem. Firstly, we decode the raw image to obtain the image we can read; secondly, we obtain the level - 0 image through image pre - processing; thirdly, we can get the level - 1 image through the radiometric correction; finally, we can attain the level - 2 image through geometry correction and provide them to the application departments .
