Application of differential SAR interferometry to the land subsidence in urban area
Synthetic Aperture Radar Interferometric technique (InSAR) is an information technology to extract the three-dimensional spatial information of ground targets on the basis of the phase data of a radar image.Currently,many departments and research institutions at home and abroad are actively engaged in the research of mechanism of InSAR and its applications,which have made many achievements.InSAR is a new promisin g research domain.With the development of Harbin city and the exploitation of groundwater in different periods,many of the subsidence phenomenon have been created in this area.InSAR is applied to the survey of the past and present ground subsidence in Harbin city,in order to provide a better guidance for subsidence prevention.
