Building characterization using polarimetric tomographic SAR data

Abstract

This paper describes the characterization of buildings using fully polarimetric tomographic SAR data at L-Band. This analysis is performed in three steps. Polarimetric tomographic data are first processed using the high resolution spectral estimator MUSIC (FP-MUSIC-1), assuming 1 scatterer. Then, points of interest are extracted using a novel signal-to-noise index. A strong reduction of artifacts is observed. Finally, detected scatterers are identified by retrieving their polarization state.
