Design and Experiment of FMCW Radar System for Drone Detection

Design and experiment of FMCW radar signal for drone is proposed in this paper. FMCW radar with operating frequency of 10 GHz is designed. The experimental study of the radar signal is done in anechoic chamber. A metal plate and commercial drone are employed as the radar targets. The triangle wave control signal with frequency of 300 kHz is employed. The voltage controls oscillate (VCO) with the bandwidth of 76 MHz is employed to generate the radio frequency (RF) radar signal. High frequency RF mixer is used to extracts the intermediate frequency (IF) of the target. The high gain parabolic antenna is employed to increase the reflected radar signal which provides long-range detection. It is found that the designed radar system provides a correct position of the targets. The targets provide difference spectrum of radar signal.
