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.
