小行星形貌特征的分析对深空探测器的导航、着陆点的选取具有重要意义。现有的深空星体形貌特征的分析与描述主要集中在火星、月球等类地天体上，而作为宇宙中为数众多、信息量丰富的小行星却鲜有文献对其形貌特征作详细深入的介绍。文章以 Vesta、Eros、Mimas 等人类已探测的小行星为例，分析了几种典型的小行星表面形貌特征，完善了凹坑、岩石等形貌特征的描述参数，并用仿真实验生成了 Mimas 小行星表面的 Herschel凹坑模型。实验结果显示，所提出的特征描述方法具有较好的仿真度和实用性。

Analysis of the asteroid topography features is of great significance to deep space probe’s navigation and selection of landing site.Most analysis and description of deep space topography features are focused on Mars, the moon and other earth-like planets.The asteroids which has great numbers and rich information in the universe are rarely introduced about its topography features in details.Taking Vesta,Eros,Mimas and other detected asteroids as an example,we listed topography surface features of several typical asteroids,improved description parameters of topography features such as craters,and use simulation experiment to generate crater model of Herschel from the Mimas surface.The experimental results show that the method to describe topography features in this paper has great simulational efficiency and practical value.
