The Processing Procedure of D-InSAR and Influence Factors of Its Application
差分InSAR处理及其应用分析

This paper introduces and studies several key steps which affect InSAR result, combined by instantiality At present, there are 4 5 SAR satellites which can be used in InSAR, especially, ERS 1/2 is the best in all SAR satellites The core procedures are as follow: sub pixel degree registration, coherence analysis, and unwrapped phase and so on The precision and noise level are important conditions which determine if InSAR can come a really useful tool, the precision of D InSAR is cm mm level in the measurement of crustal deformation, noise influence the coherence of surface feature, the coherence is lost in places of more noise
