Abstract

The radar backscattering from extraordinary poplar stands, where all the trunks are leaning towards the same direction, has been modelled. Data acquired with the JPL/AIRSAR during the MAESTRO-1 campaign have been used. At C- and L-band the backscattering is not influenced by the leaning of the trunks. At P-band the backscattering decreases at HH polarisation particularly. This can be predicted theoretically and is explained by distortion of the trunk-ground dihedral reflection. A similar effect is obtained when topography affects the backscattering
