    Design and development of K-Band FMCW radar for nano-drone detection
    (IEEE, 2020-12-04) Zulkifli, Safiah; Balleri, Alessio
    Nano-drones, are insect-like size drones with a capability of intrusion to provide intelligence and potentially violate secure establishments and public privacy rights. Nano-drones are already an existing technology which is becoming more and more available, portable, affordable and easily operated. As such, they may soon become a plausible defence and security threat. This paper presents the design and development of a K-Band FMCW radar prototype for nano-drone detection. The FMCW radar prototype consists of connectorised components operating at a carrier frequency of 24 GHz and offer high parameter selection flexibility. Experiments have been carried out in order to evaluate the system performance. Results show that a small Arcade PICO Drone Nano Quadcopter (smaller than 5 cm) could be detected, and that its micro-Doppler signature could be extracted from data.

    Detection of flying nano-drone signatures with a K-band FMCW radar
    (IEEE, 2024) Zulkifli, Safiah; Corrias, Alessandro; Balleri, Alessio
    Nano-drones are insect-like drones with a threat capability of intrusion to provide intelligence and potentially violate secure establishments and public privacy rights. They are an existing technology which is becoming increasingly more available, portable, affordable and easy to operate. As such, they represent a plausible defence and security threat. In this paper, an FMCW radar prototype operating in K-band is presented which was used to detect signatures of a flying nano drone characterised by Radar Cross Section (RCS) values below -25 dB. Results show the radar prototype was capable of successfully detecting the nano drone in flight and collecting its micro-Doppler signatures in various flying trajectories.
