Problems solved by technology
Among them, the ultrasonic sensor is easily disturbed by the sound of the propeller of the agricultural drone, and the detection distance is short
The visual sensor has strict requirements on the environment. When it is in the harsh operating environment of agricultural drones, the detection results of the visual sensor will be limited
[0004] Therefore, the method of the prior art is not suitable for the operation scene of the agricultural UAV, and cannot meet the needs of the agricultural UAV during operation.

The invention provides a flight control method of an agricultural unmanned aerial vehicle, a radar system, and the agricultural unmanned aerial vehicle. The method includes steps: controlling a rotation device (13) to continuously rotate to enable the rotation device (13) to drive a radar detection device (12) to continuously rotate; obtaining detection information of the radar detection device (12) in multiple rotation directions during continuous rotation; and controlling the take-off and landing of the agricultural unmanned aerial vehicle (30) according to the detection information. The agricultural unmanned aerial vehicle is provided with the radar system so that automatic take-off and landing of the agricultural unmanned aerial vehicle can be realized, the adapting capability of the environment is strong, and detected information is accurate.
Description
technical field [0001] The invention relates to the field of unmanned aerial vehicles, in particular to a flight control method for agricultural unmanned aerial vehicles, a radar system and agricultural unmanned aerial vehicles. Background technique [0002] Agricultural drones can automatically take off and land, and spray agricultural and forestry plants. Among them, the agricultural UAV is usually equipped with detection equipment to detect the relative height and relative speed of the agricultural UAV relative to the ground or obstacles, and then used for the automatic take-off and landing of the agricultural UAV. [0003] In the prior art, detection equipment carried on agricultural UAVs usually includes ultrasonic sensors and visual sensors. Among them, the ultrasonic sensor is easily disturbed by the sound of the propeller of the agricultural drone, and the detection distance is short. Vision sensors have strict requirements on the environment. When they are in the ...
