Radio frequency channel parallel detecting device and method for unmanned aerial vehicle

Abstract

The invention discloses a radio frequency channel parallel detecting device and method for an unmanned aerial vehicle. The device comprises a number of radio frequency modules, a number of radio frequency microcomputer modules, a general control microcomputer module and a real time clock module. The device divides the common 2.4GHz communication band of the unmanned aerial vehicle into 42 channels, and then measures the RSSI and time of each channel in parallel. According to the measurement result, the difference between an unmanned aerial vehicle signal and the RSSI of the background noise and the bandwidth characteristic of the unmanned aerial vehicle signal are used to detect the unmanned aerial vehicle, wherein the unmanned aerial vehicle signal mainly comprises an image transmission signal and a remote control signal. In addition, the device can detect the frequency hopping sequence of the remote control signal of the unmanned aerial vehicle, and further identifies the unmanned aerial vehicle model according to the frequency hopping sequence. The radio frequency channel parallel detecting device and method for the unmanned aerial vehicle have the advantages of low cost, high detection precision, simple and convenient deployment of the device structure and the like, can effectively detect and identify the unmanned aerial vehicle, and can be widely used and deployed in various areas where unmanned aerial vehicle detection is needed.

Description

technical field [0001] The invention relates to the field of unmanned aerial vehicle detection and signal detection, in particular to a radio frequency channel parallel detection device and method for unmanned aerial vehicles. Background technique [0002] In recent years, with the increasing use of small UAVs and the increasing number of UAV enthusiasts, the number of UAVs has increased rapidly, and the phenomenon of "black flying" of UAVs has become more and more serious. many. The flying height of the UAV enables it to fly over most obstacles, and can carry out high-definition image return and tracking shooting of key areas. It is used by criminals for drug trafficking, smuggling, and violent terrorist activities, which poses a huge threat to the privacy and personal safety of the country and individuals. At the same time, due to the small size and low flying altitude of UAVs, commonly used radar detection methods are often unable to detect and identify UAVs, making it ...

Problems solved by technology

The flying height of the UAV enables it to fly over most obstacles, and can carry out high-definition image return and tracking shooting of key areas. Used by criminals for drug trafficking, smuggling, violent terrorist activities, etc., which poses a huge threat to the privacy and personal safety of the country and individuals

At the same time, due to the small size and low flying altitude of UAVs, commonly used radar detection methods are often unable to detect and identify UAVs, making it impossible to detect whether there is illegal UAV intrusion in some sensitive airspaces. Due to the high cost and low utility of signal analysis equipment, it cannot be widely used in various places and areas that need to defend and detect drones
