N2 - Ground-based interferometric SAR (GB-InSAR) technology is becoming an important terrain mapping technology as it has the characteristics of short observation interval, flexible operation environment and high data precision. Compared with the other air borne/space borne InSAR system, the GB-InSAR system has different image resolution, observation geometry and observation range. Thus, based on those features above, the interferometric phase of GB-InSAR has its own particularity. Mainly shows in the small offset between master and slave image, different decoherence sources, and the low-coherence area caused by varying viewing angle. This paper propose an interferometric phase processing method in order to recognize and compensate the low-coherence area based on their multi-characteristics, and rebuild the interferometric phase by using signal-domain estimation technology. This method will provide the satisfactory interferometric phase image for the following terrain map generation.
