摘　　要：图像条带是成像光谱仪采用多元并扫方式获取遥感数据而引起的新问题之一.本文对图像条带的成因进行了初步阐述,并简要介绍了国内外现有图像条带处理的方法,着重介绍了归一化经验分布函数匹配方法工作原理,并用该方法对《神舟三号》成像光谱仪图像条带消除进行了试验.结果表明归一化经验分布函数匹配方法对《神舟三号》中分辨率成像光谱仪图像条带消除是非常有效的,图像质量明显得到改善,对以后同类仪器的资料处理具有很好的借鉴作用.Striping is new problem for imaging spectroradiometer data, which is obtained by multi-sensor scanning on spacecraft. The reason causing stripes and the development of striping removal methods were described, and the principle of matching empirical distribution functions was introduced in detail. By using this method, some experiments were done to destripe imaging spectroradiometer data of SZ-3. The result shows that the method of matching empirical distribution functions is available for destirping imaging spectroradiometer data of SZ-3, and the quality of image is improved obviously. This will help to process the future similar instruments data.
