摘要：Interferometric Synthetic Aperture Radar (InSAR) allows production of high resolution DEM and detection of small earth motions using multiple pass SAR data sets obtained by remote sensing satellite. But the digital processing to extract the DEM is quite complicated. The whole pro cedure has not yet reached sufficient efficiency and robustness to warrant automated DEM production as commonly produced by stereo vision with optical images. The automatic algorithm for precision registration is one of the bottlenecks for improving both the accuracy and the efficiency of multi-source data analysis, including the repeat-track D-InSAR processing. In this paper, an automatic approach with multi-step image matching algorithm is presented. All procedures could be automatically implemented. The primary experiment result is promising in the fast precision registration for the repeat-track In SAR data and reveals the potential of the presented automatic strategy
