Drone Defense

Low-altitude Slow Drone DefenseThe system is mainly composed of four main subsystems and modules: search system, photoelectric tracking system, radio frequency interference system and display control unit.

At present, the system architecture of the unmanned aerial vehicle defense system has been developed abroad.

Radio interference Radio interference technology interferes with the UAV positioning system or controls the radio signal, making it out of control, forced landing, hovering or returning.

What is the drone counter-control system?

1. It is mainly applicable to airports, public prosecutor's systems, prisons, detention centers, drug rehabilitation centers, confidential institutions, troops, large-scale events, concerts, important meetings, government agencies, anti-terrorism fields and other important places and facilities, and areas that need space confidentiality and drone control.

2. The anti-unmanned aircraft system consists of four main subsystems and modules: search system, photoelectric tracking system, radio frequency interference system and display control unit.

3. The so-called UAV countermeasure system, also known as the anti-UAV system, refers to a device that uses technical means to monitor, interfere, deceive, control and destroy UAVs.

4. UAV defense technology can also be understood as UAV counterattack, and there is a set of options.Combined defense system, combined with different scenarios to use different methods, Chengdu Kongyu Technology solves in detail for you

5. Interference blocking class, which is mainly realized through signal interference, sound interference and other technologies. Direct destruction, including the use of laser weapons, the use of drones to counter drones, etc. The monitoring and control category is mainly realized by hijacking radio control and other means.

Which department needs to accept the anti-drone defense system

The purchase of drone counter-control equipment requires a license. According to the official website of the Ministry of Industry and Information Technology, recently, the Ministry of Industry and Information Technology will work with the Ministry of Public Security, the Ministry of Justice, The State Administration of Market Supervision and Administration and other departments jointly carried out law enforcement actions to crack down on the illegal production, sale and use of drone radio counter-control and other equipment.

Ministry of Housing and Urban-Ral Development. The state conducts fire inspection and fire acceptance, and is assigned to the construction department.

[Legal Analysis]: It should be filed by the aviation administration department. The flight needs to be approved by the relevant departments. In order to avoid the impact on the flight safety of transport aviation, it is prohibited to engage in drone flight activities in the airspace of civil transport airports without the approval of the regional authority.

Aerial photography needs to be applied to the Civil Aviation Administration. Generally, civil aircraft flying in the air should use airspace and must report to the Civil Aviation Administration for approval. No unit or individual is allowed to carry out aviation and aerial photography activities privately without the approval of the relevant departments.

After all the installations are completed, there will usually be personnel from the fire department to carry out fire inspection. At present, the items that need to be inspected in the fire acceptance of the project are mainly: First of all, check whether the power supply introduction of the power distribution room is qualified according to the load level requirements of fire-fighting electricity required by buildings and places.

Machine scanning radar: left and right scanning, 6s circle, the radar needs to scan the object 3 times to be determined, that is to say, 6*3=18s can determine the object, which will give some drones an opportunity to take advantage of it. The anti-drone system can detect drones. The anti-drone defense system is mainly composed of a detection unit and an interference suppression unit.

How is the development status of the anti-UAV system

The technology is immature: Although UAV technology continues to develop, there are still many technical problems in actual patrols, such as the stability, flight time and data transmission of UAVs. Quality and other aspects need to be constantly improved and improved.

Therefore, in fiscal year 2022, the U.S. Department of Defense proposed to invest $3.6 billion in anti-drone research and development and $75 million in anti-drone procurement. The overall anti-drone fund increased by $3.4 billion over fiscal year 2021. Working principle Anti-drones generally involve two types of technologies: detection and restraint. Detection technology.

The third is the interference blocking class, which interrupts the communication between the drone and the remote control platform by transmitting directional high-power interference radio frequency to the drone, forcing the drone to land or return by itself.
