Description

technical field

[0001] The invention belongs to the field of aircraft early warning, in particular to the early warning of unmanned aerial vehicles, and relates to an unmanned aerial vehicle signal processing device and a signal processing method. Background technique

[0002] At present, drones have begun to widely intervene in the daily life of the masses. Since UAVs can take off and land straight up and down, and can hover in the air, the flight is more flexible. Therefore, compared with traditional fixed-wing aircraft, it has its own characteristics and has been widely used. The existing regulations are not perfect for flight management in the field of general aviation, but for drones that fly at low altitudes and are often within the line of sight, the current supervision is still blank.

[0003] Although drones have begun to give consumers a new experience in aerial photography, logistics, patrols, etc., and have a wide range of application prospects, but at the same ...
