Abstract :
Use of the fractional Brownian motion surface model within the small perturbation scattering model is explored. A new formulation of the normalised radar cross section of natural surfaces is obtained. The effectiveness of the presented model has been assessed by direct comparison with some widespread scattering models and with a set of measured data reported in literature
