In this paper, a technique that is able to reconstruct highly sloped and discontinuous terrain height profiles, starting from multifrequency wrapped phase acquired by interferometric synthetic aperture radar (SAR) systems, is presented. We propose an innovative unwrapping method, based on a maximum likelihood estimation technique, which uses multifrequency(More)
Along-track interferometric synthetic aperture radar (AT-InSAR) can be used to estimate the radial velocity of ground moving targets, starting from interferometric phase measures. The estimation obtained from a single-phase interferogram suffers from ambiguities. To solve these problems, multichannel AT-InSAR systems are required. In this letter, we analyze(More)
Recommended by Simon Watts Along-track interferometric synthetic aperture radar (AT-InSAR) systems are used to estimate the radial velocity of targets moving on the ground, starting from the interferometric phases, obtained by the combinations of two complex SAR images acquired by two antennas spatially separated along the platform moving direction. Since(More)
A single-channel Synthetic Aperture Radar (SAR) sensor produces a high resolution two-dimensional (2-D) image of the observed scene [1], representing a projection of the 3-D scene scattering properties onto the 2-D azimuth-range plane, while it's not able to obtain the reconstruction of the scene backscattering properties along the elevation direction,(More)
Some multichannel synthetic aperture radar interferometric configurations are analyzed. Both across-track and along-track in-terferometric systems, allowing to recover the height profile of the ground or the moving target radial velocities, respectively, are considered. The joint use of multichannel configurations, which can be either multifrequency or(More)
