用InSAR技术从雷达图像获取DEM的质量控制

Quality Control of DEM Generation Using SAR Images and InSAR Technique

该文阐述利用InSAR技术生成DEM的过程,比较使用不同参数处理ERS数据所获得的不同试验结果,分析了产生差异的因素,为提高处理结果精度进行了有益的尝试,最后总结出干涉处理过程中影响结果精度的三个主要因素和关键点。

This paper gives a detailed discussion of DEM generation using InSAR. Then it compares different experimental results by diverse processing measures on ERS data, and analyzes the causes. As a result, three key factors which directly produce an influence on the precision of processing result are put forward.
