UAV detection with K band embedded FMCW radar

Electromagnetic simulations of a propeller, motor and arm of a commercially available UAV are presented. The goal was to identify the incidence angles of the wave where there is a strong variation of the radar cross section of the structure due to the position of the propeller, which will help in the Doppler analysis. Additionally measurements of the UAV were performed using a commercially available 24-GHz FMCW radar. Two scenarios were considered: hovering and vertical movement. In both cases the Doppler signature is characteristic.
