Exploring Radar Micro-Doppler Signatures for Recognition of Drone Types by Jun Yan, Huiping Hu, Jiangkun Gong, Deyong Kong, Deren Li

“…We categorize small drones into three types based on their blade types: fixed-wing drones with only puller blades, multi-rotor drones with only lifting blades, and hybrid vertical take-off and landing (VTOL) fixed-wing drones with both lifting and puller blades. …”

Improved Radar Detection of Small Drones Using Doppler Signal-to-Clutter Ratio (DSCR) Detector by Jiangkun Gong, Jun Yan, Huiping Hu, Deyong Kong, Deren Li

“…Our tests include quad-rotor, fixed-wing, and hybrid vertical take-off and landing (VTOL) drones, with mean SNR values comparable to the surrounding clutter but with DSCR values above 10 dB, significantly higher than the clutter. …”
