摘　　要：雷达干涉测量技术(InSAR)以其全天候、全天时、并能快速得到DEM而引起全世界地学人员的关注。但是由于处理过程复杂及条件要求严格,目前除购买高价的商业软件外,一般的研究人员很难投入到该项技术的研究与应用中去。利用以荷兰Delft大学为主所研发的开源软件Doris来进行雷达影像生成DEM的研究,详细介绍用Doris进行干涉处理过程并提取库赛湖区域DEM,得到不亚于商业软件的干涉成果,最后对DEM精度做了对比分析。The Synthetic Apenture Radar Interferometry （InSAR） technique has aroused people＇s interest in geomorphology over the world. But because the complex processing and the conditions requested are strict, at present, besides purchasing high price commercial software, the general researcher is very difficult to go into this technical research and application. This research u- ses opens source software Doris which primarily developed by Dutch Delft University to carry on radar imaging and to generate DEM. The paper introduce＇s how to carry on the interference processes with Doris in detail and generated DEM of Kusai lake. Obtained interference results have nothing less than using commercial software. Finally the contrast analysis of the DEM precision has been made.
