Abstract
In the last years, new approaches for feature extraction from high resolution SAR images have been presented. One of them is the deterministic approach for building height retrieval from double reflection contribution on SAR images of urban areas. Actually, promising results can be guaranteed only if a high aprioristic knowledge of involved radar and scene parameters is available, but this requirement is not always satisfied. For this reason, here we investigate the influence of an imperfect knowledge of the scene on the final result of building height estimation. In particular, by means of sensitivity analyses and simulation examples, the influence on the height retrieval of an error on the knowledge of the angle between the building wall and the radar flight trajectory is investigated and discussed.
