%X This paper introduces a procedure of Interferometric SAR ( InSAR) processing, including the algorithms of image registration and phase unwrapping. A coarse-to-fine fast registration framework, based on themean square difference function, is proposed. Aiming at the interferogram with large size and dense residues, two unwrapping algorithms arepresented: one is themulti- patchesmethod to connectopposite residues, and another one the center expanding method to search opposite residues. These two algorithms can avoid long branch cuts and excessive connection of residues, and arewellemployed in the experiments ofENVISAT- ASAR datasets. Comparedwith conventionalmethods, our results of registration and unwrapping show good advantages in InSAR data processing.
