There is a conflict in radar parameter design that a rapid update rate and fast beam scanning will result in a short dwell time and poor Doppler resolution. We compared two drone radar detection systems, including Radar-α, with a rapid update rate of 1 Hz and a dwell time of 2.7 ms, and Radar-β, which has moderate numbers of 1/6 Hz and 20 ms, respectively. The detection results of quadrotor drones, DJI Phantom 4, indicate that Radar-β can detect the drone at a longer range of 11.8 km with a detection probability of 86%, much larger than that of 3.6 km and 12% using Radar-α. Furthermore, Radar-β also extracts better micro-Doppler signals (i.e., Jet Engine Modulation, JEM) produced by rotating blades of drones than Radar-α, which benefits the radar classification of radar signals of drones. Therefore, a radar with a moderate radar dwell time and Doppler resolution is a better radar solution for a counter-unmanned aircraft system (C-UAS), with high efficiency in detecting and classifying radar echoes from drones.
