Embodiment Construction

[0054] The embodiment of the present invention describes a UAV signal processing device, such as figure 1 The UAV signal processing device shown includes a receiving module 1 , a monitoring module 2 , an early warning module 3 , an interference module 4 and a transmitting module 5 .

[0055] The receiving module 1 utilizes the omnidirectional receiving antenna 17 to scan the uplink and downlink working frequency bands of the UAV for real-time scanning of UAV signals.

[0056] The monitoring module 2 includes a power divider 6 that divides the received signal into multiple signals at the same power, a band-pass filter unit 7 that performs band-pass filtering on each signal, and an A / C that converts the signal into a digital signal. A D conversion unit 8 and a spectrum analysis unit 9 that performs Fourier transform on a digital signal and changes time domain data into frequency domain data.

[0057] Early warning module 3 comprises the storage unit 10 of storing unmanned aeria...

Abstract

An unmanned aerial vehicle signal processing device and 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), an early warning module (3 ) includes a storage unit (10) for storing unmanned aerial vehicle frequency domain data and a comparison unit ( 11), when the comparison result is within the predetermined range, the early warning module (3) sends an alarm, and the interference module (4) includes a baseband signal generator (12) for setting the baseband signal frequency, a baseband signal modulated into a noise signal Interference modulator (13), operational amplifier (14) to increase noise power and combiner (15) to combine different noise frequency bands. The invention detects the working frequency band of the drone, early warning of the approaching flight of the drone and prevents the approaching flight of the drone to a protected security area.

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 ...
