【Abstract】 Synthetic Aperture Radar interferometry(InSAR) is a rapidly developing earth observation technique.Comparie with leveling and GPS,InSAR had advantages in large area,high resolution,all-weather and low cost,which enabled it to be a potential tool of deformation monitoring.In this paper,two-pass and three-pass methods to obtain the deformation interferogram of Fengfeng-Handan mine in Hebei province of China from Envisat Single Look Complex data.Further more,some limits and merits of DInSAR in deformation monitoring are discussed according to the result of interferometry.更多还原
