Abstract

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.

Description

technical field [0001] The invention designs an unmanned aerial vehicle obstacle avoidance radar device, and specifically designs a 360-degree panoramic scanning radar for unmanned aerial vehicle obstacle avoidance based on mirror reflection with reasonable structure design. Background technique [0002] Existing drones generally use vision, ultrasound or laser to avoid obstacles. When the visual solution is used, the recognition will decline when the light is dark, and it is easy to make recognition errors in bad weather such as snow, rain, and fog. The ultrasonic obstacle avoidance system can detect a very short distance, which cannot meet the needs of outdoor UAV obstacle avoidance. The cost of using lasers is high, and the recognition accuracy rate will still decline in bad weather. The millimeter-wave radar obstacle avoidance overcomes the above shortcomings, can penetrate bad weather, has a long detection distance and low cost. [0003] In traditional technology, if...
