Coregistration Based on Sift Algorithm for Synthetic Aperture Radar Interferometry

  title={Coregistration Based on Sift Algorithm for Synthetic Aperture Radar Interferometry},
  author={Fangting Li and Guoqiang Zhang and Jun Yan},
Single-look complex image coregistration is the key step of Synthetic Aperture Radar(SAR) Interferometry. The precision of the coregistration results have a direct effect on the quality of the SAR interferogram generated, thereby it will influence the accuracy of extracting DEM. In this paper, SIFT (Scale Invariant Feature Transform) algorithm will be used in Single-look complex image coregistration, and in the pilot study, experiments have provn the method is useful.
