  • Differential Synthetic Aperture Radar Interferometry(DInSAR) can only measure one-dimensional deformation of surface along Radar line-of-sight(LOS).However,surface changes always exhibit three-dimensional(3D) characteristics.This paper presents a method to estimate 3D deformation of L'Aquila earthquake by combining multi-platform DInSAR LOS data based on the imaging geometry of Radar.The characters of the surface reflected by the 3D deformation are very consistent with the geological exploration.The 3D deformation was also compared with real GPS survey,and the results demonstrate that the 3D surface deformation fields are reliable and with high accuracy.
