Characteristics of ultra-wideband radar echoes from a drone

抄録

This letter proposes to use an ultra-wideband (UWB) radar for drone detection and experimentally investigates feasibility of the proposal. First, the radar cross section (RCS) of a typical quadrotor drone is clarified. Next, radar range profiles of a flying drone are discussed. As a result, we have confirmed that an UWB radar with high range resolution can detect a drone and observed a unique feature of the echoes reflected from the drone's rotor blades. The feature will enable us to distinguish a drone from other flying objects.
