Radio full-band safety system

Abstract

The invention discloses a radio full-band safety system, which comprises an intelligent host, an anti-drone active defense civil aviation guarantee type unit, a radio full-band investigation and alarmunit, a full-band intelligent precise interference unit, a perimeter interception substation unit and a fault monitoring unit, wherein the intelligent host is used for communicating with each unit, displaying the information of each unit and controlling the operation of each unit; the anti-drone active defense civil aviation guarantee type unit is used for intelligently identifying whether a civil aviation aircraft exists in the current airspace or not, and if so, suspending the transmission of a deception signal; the radio full-band investigation and alarm unit is used for carrying out all-weather and all-time drone signal monitoring on a safe airspace; the full-band intelligent precise interference unit is used for automatically tracking the change in real time according to the change of the signal frequency of invasion equipment and carrying out precise interference suppression; the perimeter interception substation unit is used for intercepting remote sensing and image transmission signals of a drone, so that the drone cannot enter a sensitive region; and the fault monitoring unit is used for monitoring and reporting equipment states in real time. According to the radio full-band safety system, radio equipment with all frequencies within a range of 100-6000 MHz can be intercepted, the low-altitude safety of the periphery of an important area is protected, and an all-weather, all-time and all-around unmanned aerial vehicle no-fly protection area is formed.

Description

technical field [0001] The invention relates to the radio field, in particular to a radio full frequency band security system. Background technique [0002] As the UAV "black flight" incident has caused a greater security threat, people have gradually begun to pay attention to the safety of UAVs, and they have begun to understand how to counter UAVs. Since the anti-drone technology was launched, many anti-drone defense systems have been developed. Due to the wide variety of drones, many anti-drone technical means have been eliminated. With the development of anti-UAV technology, the main technologies of the anti-UAV defense system have basically matured. At present, the main technologies of the anti-drone defense system include signal jamming, laser strikes, and physical countermeasures. In terms of military UAV countermeasures, laser strikes and physical countermeasures are the main technical means; in terms of civilian UAV countermeasures, signal jamming technology is th...

Problems solved by technology

The UAV countermeasure equipment interferes with the data link and positioning system of the UAV by transmitting signal frequency, and cuts off the communication and navigation between the remote controllers of the UAV, so that the UAV automatically lands slowly or returns to the take-off point , can assist in tracking the traces of operators behind the scenes, so as to ensure the safety of low-altitude airspace. The frequency band signal range that drones can use is usually in the range of 100MHz to 6000MHz. There are thousands of communication frequency points in this frequency band, and no one is used by regular manufacturers. The signals of drones are in the two ISM frequency bands of 2.4GHz and 5.8GHz. The signals of drones of non-standard manufacturers and saboteurs cannot be specified and known, so tracking and interference cannot be carried out.

[0003] When interfering with the UAV signal, there will be civil aircraft passing by at the same time. In the prior art, the signal of the UAV is mostly suppressed for interference, resulting in the interruption of the signal of the civil aircraft, or the inability to monitor the 1030MHz / 1090MHz characteristic signal of the civil aircraft. cause an accident
