The invention discloses a mirror reflection based radar for the obstacle avoidance of unmanned aerial vehicles, which comprises a radar shell (1), a millimeter-wave radar front-end and baseband processing circuit (2), a millimeter-wave radar lens (3) and a rotating mirror (4), wherein the millimeter-wave radar front-end and baseband processing circuit (2) is arranged in the bottom side of the radar shell (1), the millimeter-wave radar lens (3) is arranged above the millimeter-wave radar front-end and baseband processing circuit (2), the rotating mirror (4) is arranged above the millimeter-wave radar lens (3), and the rotating mirror (4) is connected with a motor (5). The radar for the obstacle avoidance of unmanned aerial vehicles provided by the invention is reasonable in structure design and low in cost, and can be applied to small unmanned aerial vehicles. According to the invention, by using the advantage of millimeter-wave beam aggregation, the radar achieves 360-degree detection through a rotating lens but without using the radar, so that the structure of the motor can be simplified; and compared with phase-position radars, only a radar transceiver module is required in the invention, so that the cost is greatly decreased, and the applicability is strong.
