Performances and limitations of Persistent Scatterers-based SAR calibration

The PS calibration combines external devices, like corner reflectors, transponders and the stable targets in the scene to provide continuous monitoring of the radiometric quality of a SAR instrument. The goal is to provide, on the bases of image blocks (say 10 × 10 km), the precise geolocation and t...

Description
Summary:The PS calibration combines external devices, like corner reflectors, transponders and the stable targets in the scene to provide continuous monitoring of the radiometric quality of a SAR instrument. The goal is to provide, on the bases of image blocks (say 10 × 10 km), the precise geolocation and the radiometric calibration information. The capability of selecting such targets, their intrinsic stability and the performances achievable by a PS-aided approach are investigated in this paper.
