Abstract

The present invention provides a radar device, a wireless rotating device for a radar, and an unmanned aerial vehicle, wherein the radar device comprises: a base; an antenna assembly disposed on the base, and the antenna assembly rotating about a rotating shaft with respect to the base; an electrical energy emitting component for converting electrical energy into electromagnetic energy and emitting the electromagnetic energy; and a power receiving component disposed at an interval from the electrical energy transmitting component, wherein the electrical energy receiving component is electrically connected to the antenna component, and is rotated with the antenna assembly for converting received electromagnetic energy into electrical energy and transmitting the converted electrical energy to the antenna assembly. With the radar device, the antenna assembly can be rotated 360 degrees omnidirectionally.

Description

technical field [0001] The present application relates to the technical field of radar, in particular to a radar device, a wireless rotating device for radar and an unmanned aerial vehicle. Background technique [0002] With the rapid development of UAV technology and the improvement of radar miniaturization technology, radar has gradually become an important part of the UAV load, and the antenna component is the core component of the radar. The driving function can rotate around a rotating shaft to detect obstacles in different directions. In the prior art, a cable is used to connect the antenna assembly and an external power supply to supply power to the antenna assembly. However, in this power supply mode, due to the limitation of the cable, the rotation angle of the driving mechanism will be limited, for example, the rotation angle is only It can reach 270°, so it is impossible to realize 360° omnidirectional rotation of the antenna assembly.
