Abstract :
The Cloude model provides an approach to estimating vegetation structure parameters, such as bald Earth elevation, tree height, and canopy attenuation, using polarimetric interferometry techniques. We show that the model contains a degeneracy that allows the bald Earth elevation to be solved for reliably, but prevents accurate estimation of the other model parameters unless simplifying assumptions are made. We present results using UWB UHF data from the P-3 FOPEN sensor
