嫦娥一号月球探测卫星采用CCD相机和激光高度计,对月球表面参数特征进行了测量,获得了覆盖完整、分辨率高的全月球数字高程模型(DEM)。基于数字高程模型,可以鉴别中尺度的月球表面的地质地貌、盆地和火山等。这些新的研究成果将有益于对月球地质演化的深入研究。
Chang’e-1 lunar orbiter measured the surface characteristics of the moon using CCD camera and laser altimeters. Lunar DEM of global coverage and high resolution has been obtained. Also,on the basis of the DEM,some middle scale geological features,basins and volcano have been identified. The new results will benefit the study of the lunar evolution.
