ABSTRACT
ABSTRACT: The interferometric coherence is a key indicator of the quality of phase values in Interferometric Synthetic Aperture Radar (InSAR) processing. Accordingly, improving the coherence degree between SAR images will contribute to ensuring unwrapping smoothly and generating reliable intereferograms. In this paper, we proposed a practical registration method for improving the coherence degree between SAR images on the basis of systematically analyzing various decorrelation sources. A large number of experimental results indicate that the proposed method can obtain better quality interferograms.
