We address the problem of extracting the maximum amount of information on an electromagnetic field over a domain D<inf>O</inf> from field samples on a domain D<inf>I</inf>, with a priori information on the radiating source. The problem is faced in two steps. In the first one, the source reconstruction is dealt with by taking into account the available a(More)
The paper deals with the problem of reconstructing the height of forests from polarimetric/multi-baseline SAR data. The approach consists of optimizing an objective functional defined as the distance between the measured data and the data predicted by the model at the actual estimate of the unknowns. We indicate the role of global optimization on the(More)
In recent years, unconventional applications ranging from biomass estimation, to the detection and location of targets hidden beneath the foliage or even to the full reconstruction of three-dimensional (3D) SAR images of vegetation have earned an increasing interest for both civil and military purposes. SAR tomography allows to access such information on(More)
This paper presents a method for the partitioning of an aperture into sub-apertures preserving the performance. The technique represents a first stage towards a subarray synthesis and is based on a multi-stage approach wherein an aperture synthesis, an evolutionary algorithm, and, finally, a local search are adopted. A proper representation has been(More)
