Unmanned-aerial-vehicle-mounted direction finding device

The invention relates to the technical field of unmanned aerial vehicles, in particular to an unmanned-aerial-vehicle-mounted direction finding device which comprises a direction finding host, a damping device, an antenna array and a fixing piece. The top of the direction finding host is connected with the damping device, the damping device is used for being connected with an unmanned aerial vehicle, one end of the fixing piece is connected with the bottom of the direction finding host, and the other end of the fixing piece is connected with the antenna array. And the gravity center of the antenna array is on a gravity center line after the direction finding device is connected with the unmanned aerial vehicle. The direction finding device is mounted on the unmanned aerial vehicle, the problem that a traditional wireless communication direction finding system often has a direction finding blind area is solved, and direction finding can be carried out in a high-rise and ground multi-obstacle environment. 本发明涉及
