Abstract

The present article describes the research effort to enhance and validate a computationally efficient 3D full-wave model for electromagnetic (EM) scattering from vegetated terrains at P- and L- frequency bands. The objective is to establish a readily available 3D coherent full-wave model of scattering from realistic complex vegetation scenes that accounts for the vertical and horizontal heterogeneity and, unlike existing scattering models, fully consider wave interactions among vegetation elements and between the vegetation and the soil. Toward this goal, building on a rigorous and coherent forest ultra high frequency (UHF) 3D full-wave model that we have previously developed and validated, we 1) optimize the computational capabilities of the EM numerical solution so that it can efficiently simulate bistatic scattering from realistic large forest or agricultural terrain, 2) improve the vegetated scene representation, and 3) validate the accuracy of the scattering model after enhancements in comparison with the multilevel fast multipole method (MLFMM) implemented in the EM commercial software FEKO.
