Qinghai-Tibet Plateau (QTP) is often affected by climate change and anthropogenic activity. In this study, permafrost surface deformation is detected by time series InSAR method using high resolution TerraSAR-X images. In particularly, a sinusoidal function model is adopted in the parameter retrieving step for seasonal deformation extraction. The backscattering (σ°) of the main ground target types,...
This study presents a dynamic deformation retrieval method for differential synthetic aperture radar interferometry (DInSAR) processing. Detailed nonlinear displacement parameters are modeled and estimated for capturing the developing trends of ground movement both in time and space. In order to reduce the system disturbance errors such as atmospheres and platform deviations, the singular value decomposition...
Radarsat-2 satellite offers general users the Quad-Pol SAR image service with a resolution of 8 meters, which provides valuable data source for the research of traffic vehicles monitoring on Quad-Pol SAR images. According to the vehicle target in such new SAR images, this paper put forward a target characteristic analysis method, which is a combination of target RCS measurement and polarization decomposition...
