Abstract :
This paper presents a new method of Corner Reflector Interferometric Synthetic Aperture Radar (CRInSAR ) technique and Permanent Scatters Interferometric Synthetic Aperture Radar (PSInSAR) technique combined calculation. The algorithm uses the subsidence rates and elevation corrections calculated on the CR points as constraint for the PS network and estimate the total optimum solutions of deformation rates and elevation corrections through the parametric adjustment method in the PS network. A simulated experiment is carried out to estimate the accuracy of the new algorithm. The results show that the accuracy of subsidence rate is about 0.37mm/yr while that of elevation correction is about 0.5m. It can be inferred that the new method is reliable and can be applied to the monitoring of regional subsidence effectively.
