Abstract:
Synthetic Aperture Radar Tomography (TomoSAR) developed as a new three-dimensional (3-D) SAR imaging technique, provides the 3-D resolution possibilities in three dimensions. In this paper, state-of-the-art TomoSAR is reviewed briefly. Then the Point Spread Function (PSF) is analyzed in the 3-D wavenumber domain. Finally, the modified 3-D Range Migration Algorithm (RMA), which is suitable for processing the more general geometric TomoSAR, is presented and demonstrated with the simulations.
