摘要
探讨了利用合成孔径雷达干涉测量技术(InSAR)生成数字高程模型(DEM)的数据处理技术。首先介绍了InSAR生成DEM的基本原理,然后着重研究了利用InSAR建立DEM的关键数据处理过程,包括影像配准、相干性分析和相位解缠方法,最后给出了二幅ERS-1和ERS-2星载SAR影像数据的处理结果。
The data processing technique is studied for digital elevation model （DEM） generation by Synthetic Aperture Radar Intefferometry （InSAR）. The principle of DEM generation based on satellite SAR images is introduced. Then, the emphasis is placed on the key data processing procedures such as SAR image matching, coherence analysis and phase unwrapping method as conducted for the test area using ERS-1 and ERS-2 this paper. well. Finally, the interferometric processing and analysis are interferometric SAR image pair. The results are also given in this paper.
