英文摘要	As a component of interferometric phase, atmospheric phase influences accuracy of millimetric land deformation measurement. Though Atmospheric Phase Screen (APS) can be estimated by Persistent Scatterer Interferometric Synthetic Aperture Radar (PS-InSAR) technology, they are pseudo without consideration of actual atmospheric state and topography. This paper researches into ineffective separation of atmospheric phase in PS-InSAR methods when applied to extended cloudy area, and proposes an improved PS-InSAR processing flow by introducing Weather Research Forecast (WRF) simulations to remove atmospheric phase before interferometric phase analysis of PSI technique to obtain accurate land deformation velocity.; http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000349688103056&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701 ; Engineering, Electrical & Electronic; Geosciences, Multidisciplinary; Remote Sensing; EI; CPCI-S(ISTP); 0
