RCS Simulation of Small Multi-Rotor Unmanned Aerial Vehicle

This paper studies radar cross section (RCS) of small-target at low altitude and slow velocity. Choosing civil small multi-rotor unmanned aerial vehicle (UAV), research on its monostatic RCS simulation was carried out based on theory and commercial software. In the research, 10GHz, 30GHz and 60GHz electromagnetic waves were used to incident on 4-axis and 8-axis multi-rotor UAVs with different polarizations, and the model of blended wing body (BWB) and the model of all physical components as target were built. By choosing a simulation scheme based on combination of theoretical analysis and bottom algorithm of commercial software, the simulation results of monostatic co-polarization RCS were obtained.
