Abstract

Phase unwrapping-the key step of interferometric synthetic aperture radar (InSAR) signal processing-is discussed

and a new method is proposed which is based on residues recognition and modified loop-integration.The validity of the new method is verified with the simulated and real data.Finally

a comparison of the processing results for the real data between the modified loop-integration

branch-cut and region-growing is presented

and a comparison of their performance is also given.
