摘　　要：研究了利用月球表面的数字高程模型和对应的卫星影像;分析了遥感图像像元亮度值与光辐射照度、月面地形(像元地面坡度、坡向)之间的定量关系;研究了月面遥感数字图像地形辐射改正的原理方法并实现月面遥感数字图像的地形辐射改正,生成无阴影正射月表遥感图像。In lunar remote sensing imageries,irregular terrain causes the change of relative orientation between image pixels and solar radiance.It is topographic influences that lead to various solar radiance received by slope surface,further to various values of pixels in lunar remote sensing imageries.Topographic correction of lunar remote sensing image is to produce ortho-rectification remote sensing image by correcting the values of pixels on slope surface to that on horizontal surface in the same solar condition（with same incidence/extend angles and distances）.In this paper,the theory of topographic correction of lunar remote sensing imageries has been proposed,and the relationship between values of pixels and terrain（including slope and aspect） has been quantitatively analyzed.An experiment of lunar remote sensing data demonstrated the satisfied correction results.
