Study of soil respons under a vegetation layer using TomSAR data and ground-based TomSAR data

International audienceThis paper proposes to first use simulated Polarimetric Tomographic Synthetic Aperture Radar (PolTomSAR) data to spatially discriminate and characterize the ground signature under a vegetation layer. The ground signature estimated from the tomogram will then be analyzed to and the influence of the different scattering mechanisms on the entropy and SPAN simulated values at soil height, then simulated data are compared to measurements acquired by a ground based SAR system
