Interferometric synthetic aperture radar (InSAR) extracts phase information from two complex SAR images to get DEM (Digital elevation map). The technique has been widely used in topography mapping, forest monitoring, and agriculture survey. Phase unwrapping is a key step in InSAR data processing. It directly influences the precision of the final elevation. Up to now, more than 40 phase unwrapping...
PolInSAR data is a good example of a high dimensional SAR data. A blind filtering of these data does not make use of possible constraints imposed by the scattering process. In this paper it is shown that the scattering over forested areas induces some constrains on the data that can be fruitfully exploited to improve the final filtering, with que consequent improved of the quantitative estimation...
