Magnitude and Spectrum of Electromagnetic Wave Scattered by Small Quadcopter in $X$ -Band

Estimation results of the magnitude and spectrum of electromagnetic wave scattered by small unmanned aerial vehicle with a radar cross section (RCS) of 0.01 m
²
obtained by numerical simulation and direct measurements in an anechoic chamber at a frequency of 9 GHz and their comparison are discussed. Effectiveness of the parasitic leakage suppression technique at small RCS measurements has been shown.
