The Role of Nonlocal Estimation in SAR Tomographic Imaging of Volumetric Media
IEEE Geoscience and Remote Sensing Letters, 2018This letter analyzes the impact of the accuracy of estimation of the data covariance matrix in synthetic aperture radar tomography of vegetated areas. The characterization of volumetric areas requires a robust estimation of the covariance matrix, which is usually performed by means of an averaging operation of neighboring pixels.

Evaluation of a bilateral filtering approach for tomographic SAR denoising
2016This work proposes to evaluate the effects of a spatially adaptive filter called NDSAR-BLF (N-Dimensional SAR Bilateral Filter) on scatterer separation and height estimation from SAR tomograms. We have developed a spatial simulation procedure allowing to generate a tomographic image stack from a simple 3D building model, assuming a multi-track airborne

Polarimetric SAR tomographic of forest scenarios
2009In this paper a technique is described for the joint exploitation of several multi-polarimetric SAR images, to the aim of yielding a separate tomographic reconstruction of each of the different Scattering Mechanisms (SM) (such as ground and volume scattering ) that contribute to the received signal. Under large hypotheses it will be shown that the data

Information extraction form tomographic SAR data
2006This paper describes the extraction of information from polarimetric tomographic SAR data. This analysis is performed inthree steps. Polarimetric tomographic data are first processed using a Capon-based vectorial spectral analysis technique,in order to extract physical and geometrical information over vertical structures.

4-D SAR support based tomographic imaging
2016SAR Tomographic techniques have been successfully used for separating the contribution of multiple coherent scatterers lying in the same range azimuth resolution cell, but usually they assume stationary scatterers and does not account for phase variations due to time deformation and/or dilation.
