Abstract :
SAR tomography allows the three-dimensional (3D) reconstruction of the reflectivity profile of the observed scene on the ground. It is based on the acquisition of several images of the same scene, collected with different view angles along slightly different orbits of the SAR platform. The spatial resolution in the elevation direction obtained with conventional Fourier-type techniques is related to the overall baseline extent of the acquisition orbits. Recently a tomographic technique denoted as Compressive Sampling Tomography (CST) has been introduced. It allows a drastic reduction of the number of acquisitions required and attains an increased resolution in the elevation direction. It exploits the sparsity property of the reflectivity profile in the elevation direction. In this paper some results obtained by applying CST to COSMO-Skymed real data are presented.
