Abstract:
The Capon algorithm can be applied to reprocess SAR images, resulting in super-resolution super-resolution reconstructed scenes with lower sidelobe levels. Base on this idea, we have proposed a processing chain of Super-Resolution Persistent Scatterer Interferometry (SR-PSI), to increase PS density. In this paper, we review the main aspect of SR-PSI. In addition, we propose a revised robust Capon algorithm, which mitigates the edge effect introduced by the Digonal Loading approach. Then we applied revised-robust-Capon based SR-PSI to a stack of Sentinel-1 data. The results show that the SR-PSI is more effective with respect to the traditional PSI.
