Abstract

The paper describes a method for phase unwrapping of interferometric SAR (synthesize aperture radar). The method use edge detection techniques to find the location of the phase jump (fringe lines) in the interferogram. Here, we combine the fringe detection and tracking to improve the accuracy of the fringe location. Then, a method of the phase correcting is also given to correct phase leap. The method given the paper has advantages of stability and less error spread. Finally, by using the L band data of SIR-C of the Three-Gorge area of China, the data of phase unwrapping are obtained by the method.
