Abstract: In this paper, experimental results of micro-Doppler effect on a multi-rotor drone with digital television based passive radar are discussed. First, the bistatic passive radar micro-motion model of the drone is established. Second, key techniques of micro-motion signal extraction are briefly described. Finally, the experimental process is introduced, including experimental scene configuration and analysis of typical experimental results of micro-Doppler effect. The experimental results agree with the theoretical analysis of the motion parameters of the drone, thereby confirming the technical feasibility of detecting the micro-Doppler effect of the multi-rotor drone using the digital television based passive radar.
