Title
Application Study of PS-DInSAR Technique Fusing Multi-metadata in Urban Ground Deformation Survey
Abstract
PS-DInSAR technique fusing multi-metadata and its basic flow are expounded considering limitations of conventional D-InSAR in atmospheric delay and space-time decoherence. It is held that multi-metadata helps to weaken the influence of systematic error and improve the surveying precision and model steadiness of PS-DInSAR. Tianjing City is surveyed in PS-DInSAR fusing ENVISAT ASAR from 2003 to 2007,GPS,SRTM3-DEM and leveling data, which greatly weakens the influence of atmospheric delay, space-time decoherence and systematic error. The precise deformation of the studied area in that period is obtained.
