Building profile reconstruction using TerraSAR-X data time-series and tomographic techniques
Résumé
This work aims to show the potentialities of SAR Tomography (TomoSAR) techniques for the 3-D characterization (height, reflectivity, time stability) of built-up areas using data acquired by the satellite sensor TerraSAR-X. For this purpose 19 TerraSAR-X single-polarimetric multibaseline images acquired over Paris urban area have been processed applying classical non-parametric (Beamforming and Capon) and parametric (MUSIC) spectral estimation techniques.
