Abstract

The invention relates to a method and device for realizing direction finding and positioning of radio signals by a multi-rotor (multi-shaft) aircraft. The invention aims to realize direction finding and positioning of radio signals from the air, utilizes the structural features of the multi-rotor (multi-shaft) aircraft, mounts direction-finding antennas on the rotor arms to compose a direction-finding antenna array, thus realizing the direction finding and positioning method and device of radio signals.

Description

1. Technical field [0001] The invention belongs to the field of radio monitoring and direction finding, fully utilizes the structural characteristics of a multi-rotor (multi-axis) aircraft, installs a direction finding antenna on an aircraft arm to form a direction finding antenna array, and realizes direction finding and positioning of radio signals. 2. Background technology [0002] With the rapid development of my country's urban construction and the increase of various radio facilities, the incidents of normal communication being interfered by radio are also increasing. When radio waves propagate on the ground, they will become chaotic due to the refraction and reflection of various media; when they propagate in the air, there is almost no reflection and they are direct. This feature makes the position and direction of the interference source obtained by aerial monitoring almost the most real and accurate information. In addition, the aircraft that implement aerial moni...
