Abstract

The CBFM technique is applied to enhance the performances of a 3D full-wave model, based on the volumetric integral representation of the electric field, for electromagnetic scattering from forest environments. This paper addresses different approaches adopted to improve the performances of the CBFM when applied to this 3D model. These approaches encompass the implementation of the CBFM on a non-uniform mesh depending on the dielectric properties of the trees, the diagonal representation of the macro basis functions and the hybridization of the CBFM with the ACA while generating the final reduced matrix.
