3D SAR Imaging of a Forest Using Airborne MB-SAR Data at L- and P-band: Data Processing and Analysis

Using a time-domain back-projection based focusing algorithm in combination with three tomographic focusing techniques (multilook standard beamforming, robust Capon beamforming, and MUSIC) a 3D volume containing a forested area has been tomographically imaged at L- and P-band. In this paper, we present further results and insights obtained by processing and analyzing these data sets with respect to the localization of the scattering sources using the three different focusing techniques, as well as for both, the two frequency bands and the different polarimetric channels.
