Unmanned aerial vehicle signal processing device and signal processing method

Abstract

The invention provides an unmanned aerial vehicle signal processing device and a processing method thereof. The device comprises a receiving module (1), a monitoring module (2), an early warning module (3), an interference module (4) and a transmitting module (5). The early warning module (3) comprises a storage unit (10) which stores unmanned aerial vehicle frequency domain data and a comparison unit (11) which compares current frequency domain data transmitted by a frequency spectrum analysis unit (9) with the unmanned aerial vehicle frequency domain data stored in the storage unit (10). The early warning module (3) alarms when the comparison result is in the preset range. The interference module (4) comprises a baseband signal generator (12) which sets baseband signal frequency, an interference modulator (13) which modulates a baseband signal into a noise signal, a working amplifier (14) which increases noise power and a combiner (15) which combines different noise frequency bands. Close-up flight of an unmanned aerial vehicle can be warned in advance by detecting working frequency range of the unmanned aerial vehicle, and close-up flight of the unmanned aerial vehicle to the protected security area can be prevented.

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 ...

Problems solved by technology

The online monitoring system disclosed in this patent document can allow ground operators to grasp the flight status of the unmanned helicopter in real time, but it requires the cooperation of airborne equipment, and cannot realize the early warning function, nor can it suppress the signal of the drone
