The research on deformation monitoring using Multi-Temporal InSAR

Since differential synthetic aperture radar interferometry (D-InSAR) based on repeat orbits technology comes out, it is applied and studied positively afterwards, however, the conventional D-InSAR technique is vulnerable to be affected by loss coherence of temporal and spatial and atmospheric retardation, it is difficult to obtain accurate deformation and apply widely in practice. Permanent scatterer (PS) technology and small baseline (SB) technology overcome the constraints of above problems effectively. This paper combines the two technologies very well, finally an experiment based on Multi-Temporal InSAR (MT-InSAR) is conducted to extract the deformation over Taiyuan area from 2005 to 2009.
