这封信提出了使用超宽带（UWB）雷达无人机检测和实验研究的建议的可行性。首先，一个典型的四旋翼无人机的雷达截面（RCS）澄清。接下来，讨论了飞行无人机的雷达距离剖面。因此，我们已经证实，具有高距离分辨率的UWB雷达可以检测到无人机，并观察到无人机旋翼叶片反射的回波的独特特征。该功能将使我们能够将无人机与其他飞行物体区分开来。
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.
