Problems solved by technology
[0002] The UAV transmits electromagnetic waves and receives echoes through the antenna and electronic components built in the radar for target detection. Since the electronic components generate heat during operation, it is easy to cause its own temperature to rise, exceeding the upper temperature limit for its stable operation, which affects the radar. use
However, the existing heat dissipation method by adding auxiliary heat dissipation devices such as heat sinks, heat pipes, and fans will increase the volume and weight, and is not suitable for heat dissipation of UAV radars with high volume and weight requirements.

The invention provides a rotating radar (100) and an unmanned aerial vehicle (1). The rotating radar (100) includes a rotating base (60), a radar control board (50), an antenna bracket (40), and an antenna (30 ), a gap is set between the radar control board (50) and the antenna bracket (40), the antenna (30) is arranged on the antenna bracket (40), and the rotating base is used to support and drive the radar control board (50), the antenna bracket ( 40), and the antenna (30) rotates, and at least one deflector (70) is arranged on at least one side of the radar control board (50), and the deflector (70) is used to guide the airflow into the set when the rotary radar (100) rotates. said gap. The rotation of the deflector (70) is driven by the rotation characteristic of the rotating radar (100), and the air flow is introduced into the gap between the radar control board (50) and the antenna bracket (40), and the radar control board (50) is taken away. The heat on the surface of the ) achieves the purpose of heat dissipation, and realizes the continuous and stable work of the rotating radar (100) used by the UAV (1).
Description
technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a rotating radar and an unmanned aerial vehicle using the rotating radar. Background technique [0002] The UAV transmits electromagnetic waves and receives echoes through the antenna and electronic components built in the radar for target detection. Since the electronic components generate heat during operation, it is easy to cause its own temperature to rise, exceeding the upper temperature limit for its stable operation, which affects the radar. use. However, the existing heat dissipation method by adding auxiliary heat dissipation devices such as heat sinks, heat pipes, and fans will increase the volume and weight, and is not suitable for heat dissipation of UAV radars with high volume and weight requirements. Contents of the invention [0003] In view of the above, it is necessary to provide an improved rotating radar and an unmanned aerial vehicle using ...
