| Abstract: | Traditional surface subsidence monitoring technologies, for example, Global Positioning System, Precise Leveling and Geotechnical Measurements, have the limitation of low spatial resolution, small coverage and high cost. D-InSAR, which was developed in recent years, is introduced to monitor the surface subsidence in this paper. The principle of InSAR and process of D-InSAR were described in detail. Moreover, the deficiencies of D-InSAR were described too. |
