Abstract
In the recent years, multi-channel Interferometric SAR (InSAR) techniques have proved to be effective in reconstructing the Digital Elevation Model (DEM) by unwrapping the interferometric phase. Commonly, multi-baseline or multi-frequency configurations are adopted for this aim. In this paper, the possibility of jointly exploiting multi-baseline and multi-frequency approaches for SAR interferometry in Ground Based (GB-SAR) configuration is addresses. An analysis of the achievable performances has been carried out, by exploiting both Cramer-Rao Lower Bounds (CRLB) and Error Lower Bounds (ELB).File in questo prodotto:
