Permanent scatterers in SAR interferometry
Differential SAR interferometry (DInSAR) is an unique tool for low-cost, large-coverage surface deformations monitoring. As well known, the technique involves interferometric phase comparison of SAR images gathered at different times and has the potential to provide millimetric accuracy. Though temporal decorrelation and atmospheric dishomogeneities strongly affect interferogram quality, reliab...
متن کاملDetection of Multiple Scatterers in Sar Tomography
Due to the capability to provide direct physical measurements, interferometry is among the remote sensing techniques that have most pushed the applications of SAR to a wide range of scientific areas and have provided direct returns for our society in terms of improved security. Repeat pass DInSAR and, more specifically, its evolution to Persistent Scatterers Interferometry (PSI), which allows t...
متن کاملRelevant Scatterers Characterization in Sar Images
Recognizing scenes in a single look meter resolution Synthetic Aperture Radar (SAR) images, requires the capability to identify relevant signal signatures in condition of variable image acquisition geometry, arbitrary objects poses and configurations. Among the methods to detect relevant scatterers in SAR images, we can mention the internal coherence. The SAR spectrum splitted in azimuth genera...
متن کاملGround Deformation Monitoring Exploiting SAR Permanent Scatterers
The detection of ground deformation phenomena exhibiting a time non-uniform behavior by means of the Permanent Scatterers technique is addressed in this presentation. Simple but effective models are discussed showing significant results obtained.
متن کاملDetection and Tracking of Prominent Scatterers in SAR Data
Tracking prominent scatterers provides a mechanism for scene-derived motion compensation of Synthetic Aperture Radar (SAR) data. Such a process is useful in GPS-denied environments where a lack of precise sensor position data makes standard motion compensation difficult. Our approach to sensor positioning estimates range histories of multiple isolated scatterers with high accuracy, then perform...
