Analysis of forest-slab height inversion from multibaseline SAR data

Abstract

We address the problem of reconstructing parameters regarding the vertical structure of forests from multibaseline SAR data. The attention is focused on the retrieval of the forest height so that the case of vanishing ground scattering is considered. The cross-spectral density of the scattered field is taken as datum of the problem and the forest height is searched for by tackling an optimization problem. An analytical and numerical analysis of the involved functional is performed by taking due care to the discrete nature of the scatterers.
