Configuration of an X-band FMCW Radar Targeted for Drone Detection

Abstract

This paper discusses the detection of drone with Frequency-Modulated Continuous-Wave (FMCW) Radar system. The system employs 11GHz to 11.15GHz frequency bandwidth to generate sawtooth linear wave through bistatic antennas with the gain of 33.7dBi, and the output transmitter power is 35dBm. Metal baffles were placed between and each side of the antennas to minimize the direct path interference. The system also includes digital down converter to obtain IQ signal with minimum mismatch. In the actual performance measurement, the drone signal was detected up to more than 500m distance in real-time with the error of less than 0.1%. The data has been saved as bin file and then later processed with MATLAB.
