Theoretical Model of the Signal Reflected from Rotating Blades of Aerial Targets

Abstract

The theoretical model representing the signal reflected from rotating blades of aerial objects with different rotor configurations is described. The proposed model is used concerning the radar operating in UHF-band for simulation of the reflected signals from the propeller-driven airplane, helicopter, and small multi-rotor drone. The simulation results are compared with the real data recorded by a passive radar utilizing signals of second-generation terrestrial digital video broadcasting standard for target illumination.
