Analytical modeling and numerical validation of forward scattering for radar applications

The forward scattering phenomenology is investigated in this work, providing a straightforward electromagnetic analytical model valid also in near-field conditions. A typical configuration useful for forward scatter radar operational scenarios, where a metallic object is illuminated while crossing a baseline, is considered. The effects of different target sizes on the scattered signal are evaluated and discussed. A full-wave numerical solution is also developed through the implementation with a commercial tool to validate the proposed analytical formulation.
