Abstract

Synthetic Aperture Radar interferometry (InSAR) is a rapidly developing technique for earth observation. Differential InSAR (D-InSAR) technique, based on InSAR, is a new method for earthquake deformation detection and land subsidence monitoring. In this paper, an innovative method of generation of interferogram for D-InSAR based on contoured correlation interferometry (CCI) is presented, which may directly generate interferogram with almost no speckle noise or blurring. The data processing results of the Mani earthquake indicate that D-InSAR CCI method can effectively reduce or even remove the decorrelation noise, even in the area with serious decorrelation.
