This paper presents both simulation and experimental results of micro-drone rotor blade electromagnetic scattering. The focus of this work is investigating the variation of these reflections as a function of variables such as polarization, frequency and azimuth angle. The simulation results clearly show a strong variation in scattering with azimuth and frequency. Experimental validation of these variations was investigated and similar trends in azimuth were found. The Doppler components from an operational micro-drone in varying polarizations are shown, these demonstrate the expected signals received by a real radar system.
