Abstract
Surface deformation has become a global problem.The traditional geodetic technique is increasingly proved to be incapable of monitoring the large-scale and serious surface deformation.The new radar interferometry technique provides an effective tool for the large coverage area and a high spatial and temporal resolution for the monitoring.This paper describes the synthetic aperture radar(SAR) interferometry technique for surface deformation monitoring.The time series method based on the permanent scatterers technique is also discussed in detail with Tianjin as a test area.The result of the test shows that the time series method has a very good application value.
