摘　　要：雾滴的散射通过三个方面对图像产生影响:雾滴对成像光线的透射衰减,空气光即非成像光线的散射及雾滴的多次散射。本文根据卫星图像中雾的特点及其对图像的影响,通过分析提出一种去雾的方法,该方法克服现有去雾模型的局限。实验表明该方法取得很好的去雾效果。The scattering of fog particle influence the images by three aspects ： the attenuation of object light, the scattering of air light and the multi - scattering of fog particle. The paper brings forward the method of filtering the fog which is based on the character of the fog of satellite images and its influence on the images. The method conquers the limitation of the present models. The experimental results show clearly that the method fihers well the fog of satellite images.
