Abstract
The atmospheric phase delay due to tropospheric water vapor has been one of the major limitations for the application of high precision repeat pass InSAR. In this paper, we present the atmospheric correction methods and key technology for ASAR interferograms with MODIS integrated water vapor data, then, conduct the atmospheric corrections using ASAR interferometric pair over the Taiyuan region as examples. The experimental results show that the MODIS\ASAR atmospheric correction method can greatly improve the quality of interferogram, and the deformation inversion accuracy can be significantly improved, verify the necessity and reliability of MODIS and ASAR data fusion for obtaining information of surface deformation.
