PALSAR Interferometry for Urban Subsidence Monitoring:An Ezperiment in Shanghai Area
In this paper,we apply the Advanced Land Observing satellite (ALOS) PALSAR data to study the urban subsidence condition in Shanghai,China. The baseline condition,troposphere delay,DEM accuracy mainly limit the capability of PALSAR interferometry,and the influences are evaluated.Six interferograms are analysed in this research,based on D-InSAR technology.We introduce a polynomial to fit the orbit error in each interferogram. After that we use a weighed interferogram stacking method to reduce the influence of atomospheric delay,and to evaluate the mean deformation rate as well.
