Abstract

In this paper, inversion of synthetic aperture radar data is dealt with and, in particular, the problem of reconstructing forest height is addressed. The forest is modelled as a random volume of particles over a rough ground. Under this model, the forest height turns out to be related to the bandwidth of the scattered field. The inversion is cast as an optimization one. Preliminary results using DLR-ESAR experimental SAR data are shown
