SPATIAL AND TEMPORAL CHARACTERIZATION OF AGRICULTURAL CROP VOLUMES BY MEANS OF POLARIMETRIC SAR TOMOGRAPHY AT C-BAND

In this paper, agricultural crop volumes are analysed using (polarimetric) tomographic SAR methodologies. A procedure for the separation of the ground and volume multibaseline coherences is proposed. This separation is used in particular to investigate the polarization dependency of the vegetation vertical structure in order to get first insights about orientation effects. This analysis has been carried out for different crops and on different development stages. The presented results have been obtained by processing a multibaseline fully polarimetric data set purposely acquired at C-band by the DLR’s airborne sensor F-SAR in 2014.
