The invention discloses a micro unmanned aerial vehicle millimeter-wave radar. The radar comprises a frequency synthesizer, a transmitter, a transmitting antenna, a receiving antenna, a receiver and a processor. The frequency synthesizer generates radar signals, the transmitter amplifies the radar signals and transmits the radar signals to the transmitting antenna to be radiated in space, the receiving antenna and the receiver receive target reflection signals, and the processor reversely deduces target parameter information in the received signals and sends the target parameter information to an unmanned aerial vehicle. A radio frequency part of the frequency synthesizer, the transmitter, the transmitting antenna, the receiving antenna and a radio frequency part of the receiver are integrated in a radio frequency front end, and a base band part of the frequency synthesizer, a base band part of the receiver and the processor are obtained through a base band plate. The millimeter-wave radar is used for detecting targets and completing parameter reverse deduction, assists the unmanned aerial vehicle in fixed-height work and obstacle avoiding, and solves the problems that an existing ultrasonic or light stream detection device is short in detection distance, is interfered with easily and does not have all-time all-weather work capacity.
Description
technical field [0001] The invention relates to the technical field of millimeter-wave radar, in particular to a millimeter-wave radar for a miniature unmanned aerial vehicle. Background technique [0002] Existing drones use ultrasonic or optical flow technology to achieve height measurement or obstacle detection, but due to the short detection distance, they are easily disturbed, and they do not have the ability to work all day and all day, so they cannot better assist unmanned vehicles. The machine completes the height-fixing operation and obstacle avoidance functions. [0003] The publication number is: CN 105334515A, and the name is: A patent for UAV obstacle avoidance radar based on mirror reflection discloses a millimeter-wave radar scheme that realizes 360-degree panoramic scanning by rotating the mirror surface. First, the radar is not suitable for altitude Secondly, in terms of obstacle detection, it can realize 360-degree panoramic scanning, but the rotation mech...
