A drone counter gun is a device specially used to interfere with or destroy illegal drones.With the popularization of UAV technology, unmanned aerial vehicles have played an important role in many fields, and they have also brought security risks.As a response measure, the development and application of drone counter-guns have received widespread attention.The following is the specific analysis：   The working principle of drone anti-gun   Signal interference: The drone counter-gun interferes with the remote control signal of the drone by transmitting a radio signal of a specific frequency, causing it to lose control. Direct destruction: Some drone countermeasures guns have the ability to directly physically destroy, such as directly capturing or shooting down drones by launching nets or other physical means. Scope of application of UAV anti-gun   Public safety: Use it around important facilities such as airports and government agencies to prevent illegal drones from posing a threat to safety. Military application: Used in sensitive areas such as military bases to prevent the enemy from using drones for reconnaissance or attacks. Advantages and challenges of drone anti-gun control   advantage： High efficiency: It can quickly intervene in the activities of illegal drones and effectively protect the safety of airspace. Flexibility: According to different environments and goals, the interference frequency and intensity can be adjusted. challenge： Technical problem: How to accurately identify and only interfere with illegal drones to avoid affecting legal drones. Legal risks: The use of drones to counter guns may involve legal issues and must comply with relevant laws and regulations. Future development trends   Technological progress: With the development of UAV technology, the technology of UAV anti-gun will also continue to progress, improving the interference accuracy and efficiency. Perfect regulations: It is expected that more laws and regulations on the use of drones will be introduced in the future to regulate the use of anti-drone guns. In summary, as an emerging defense equipment, UAV anti-gun plays an important role in protecting the safety of airspace.However, its use also faces technical challenges and legal restrictions.Therefore, continuous technological innovation and reasonable regulatory formulation are essential to ensure the effective and compliant use of drone countermeasures.  

Every next second of life is unknown, but it can be benign.The drone "black fly" incident is boiling over, but we are still the only ones waiting for us.       According to U.S. media reports, a U.S. airliner and a drone passed by a few days ago, only about 30 meters apart. Fortunately, there was no accident.     On July 31st, at New York's John F. Kennedy International Airport, the Delta Air Lines MD88 passenger plane carrying 5 crew members and 154 passengers was flying to the runway to land. The pilot suddenly noticed a drone southwest of its right wing.     According to the Federal Aviation Administration, the pilot said to the command center at the time: “There is a drone flying on the southwest side of the aircraft."The command center asked, “What is the flight altitude?"”I think it's 100 feet (about 30 meters) below me, just below the right wing.""Then, the command center reminded the next plane: "Be careful, the one in front of you reported that a drone was found."”     The pilot did not avoid and dodge in the end, but fortunately, the plane landed safely without an accident.     Earlier this year, a drone flew at an altitude of about 2,700 feet (about 823 meters) over Brooklyn, New York, forcing an airliner flying at Laguardia Airport to climb 200 feet (about 61 meters) in order to dodge.     With the increase in the number of drone accidents, the U.S. Federal Aviation Administration has launched an action to call on drone enthusiasts to stay away from airports.   The airport may be vast and have a good view in the eyes of drone enthusiasts.As a result, many people ignore discipline and go to the airport to control drones with a sense of luck. Indeed, this loophole has caused many accidents. However, one thing falls and one thing falls. Nuoanyue's low-altitude slow-speed small-target drone defense system mainly targets this situation and uses powerful detection equipment as a safety escort to nip all flying threats in the bud.  

The convenience and benefits that drones bring to us are immeasurable, but at the same time the losses they bring to us are also huge.In recent years, the situation of “black flying” of unmanned aerial vehicles has become more and more serious. Its impact has not only disrupted the air management order, affected the safe flight of civil aviation, but also interfered with the normal air training of troops, occupied the army's combat readiness resources, and consumed a lot of manpower and material resources. It poses a serious real threat to the capital's air defense security. With the attention paid to the “black fly” incident of drones, a series of anti-drone work has also been followed up, and the anti-drone system has played a key role . The interference of the “black fly” of drones on the airport is the most serious, so many airports have set up a number of drone monitoring sites, and the fixed anti-drone defense system further guarantees safety. Generally, drones fly at low altitudes and slow speeds. Coupled with their small size, it is inevitable that the visual range of the supervisory personnel will be drilled. Loopholes, and with the assistance of the fixed anti-drone defense system, the fish that missed the net will not be missed. Nuoanyue low-altitude slow-speed small target drone defense system-fixed is a version developed to deal with the security threats of small drones and respond to emergencies.The product can realize the engineering deployment in fixed areas, and realize the 24-hour unattended 24-hour integration of automatic detection, automatic tracking, and automatic attack.The equipment is modular in management and simple in operation, and can be quickly assembled and deployed according to the actual situation.Automatically detect the drone by radio or radar, track and lock it, interfere with the drone's data link and positioning system, cut off the drone's navigation, and communicate with the remote control, thereby forcing the drone to land automatically or drive it away to ensure the safety of low-altitude airspace.  

As the use of drones as data acquisition equipment is increasing, the commercial use of drones is also growing rapidly as a result.With the advent of the Fourth Industrial Revolution, drones will have an impact in the biological, technological and physical fields.At the same time, cost reductions and technological advances have allowed drone applications to continue to expand.Its technology is used in booming industries and fields, including safety, construction, agriculture, entertainment, land management, etc., and is still growing. The rise of commercial drones has inevitably brought some negative effects. Some individuals and teams have begun to use drones for malicious attacks on a global scale. Many black fly incidents have brought major security risks to the no-fly field and high-security areas. Many companies are paying attention to this trend and trying to enter the anti-drone technology industry.They introduced various anti-drone equipment, such as anti-drone guns, radio signal interference, etc.     Here we focus on the anti-drone gun and its principle.An anti-drone system launched by Nuoyue Technology-portable, that is, an anti-drone gun. The working principle of this anti-drone gun is as follows：     The product is small in size, light in weight, easy to carry, and simple to operate, and can be quickly assembled and deployed according to the actual situation.By interfering with the data link and positioning system of the UAV, the communication and navigation between the UAV and the remote control are cut off, thereby forcing the UAV to land automatically or drive it away to ensure the safety of low-altitude airspace.The transmission power is adjustable, the interference distance is 800~1000 meters, and the interference direction angle is large, so there is no need to aim accurately.      

According to reports from foreign media, the Chinese Air Force has formed a force dedicated to detecting and disposing of drones.     According to a report by the "China Daily" quoted by the website of Japanese diplomatic scholars, the People's Liberation Army Air Force said in a press release that this force is mainly used to deal with slow and small flying targets whose flight altitude is generally below 1,000 meters.     The wording of "China Daily" makes it look like military drones are its main target.The report mentioned that the new troops have been practicing how to deal with drones used in “reconnaissance, infiltration or offensive operations.”It also said that small drones that are difficult to detect by radar “may pose a great threat to important targets.”     However, with UAVs flying slowly at low altitudes as the main goal, it shows that the People's Liberation Army Air Force is likely to spend most of its time dealing with UAVs operated by its own people.     The report said that while this new force was exposed, China, which has experienced several hidden dangers, was considering how to best control drones used by civilians.     In November last year, a drone was found to be flying near a military airport in Hebei Province without approval.The People's Liberation Army Air Force forced the drone to land and confiscated it by the police.     In another incident, an unapproved drone flew near an airport in Zhejiang Province, forcing the airport to close for nearly an hour.     The report did not disclose details, but said that there are still some unapproved drone flight activities that have interfered with military aircraft training.All drones involved are civilian.According to reports, the offending drones are “owned by private companies, aviation enthusiasts, and individual airlines.”     The report said that these incidents seemed to be the reason for the new anti-drone unit of the People's Liberation Army Air Force.     In November last year, shortly after the drone “black fly” incident occurred at a military airport in Hebei, Shen Jinke, a spokesperson for the Air Force of the People's Liberation Army, said that the Air Force will work with civil aviation, public security and other departments to further strengthen the control of “low, slow and small” aircraft to ensure air safety.     Shen Jinke said: "In recent years, some enterprises and individuals have repeatedly banned the illegal flight of ‘low-speed and small’ aircraft... some endanger the safety of military and civil aviation and public safety.”     Current Chinese law stipulates that the operators of drones must obtain approval before they enter the air to fly, but many people seem to have turned a deaf ear to this provision.     In 2014, a source interviewed by The Wall Street Journal said that about 80% of China's drone flight activities have not been approved.In response to this problem, China has been considering stricter measures, such as requiring drone operators to register in a national database.     The report said that there are currently about 100,000 privately owned drones in China, and China's drone industry is expected to develop rapidly in the next ten years.     Of course, China is likely to also pay close attention to the development of military drones.     According to a study by the New America Foundation, 86 countries around the world “possess a certain degree of drone capabilities.”  

With the development of science and technology, military competition in various countries around the world has become more intense. The development of the field of unmanned aerial vehicles has also promoted the development of science and technology, and at the same time it has also brought security risks to society. Therefore, the anti-DRONE technology has been developed.Nuoanyue Technology anti-drone launched a low-altitude slow-speed small target defense system AUAV.     Most consumer drones rely on GPS and radio links for navigation, and interference or hacking is an elegant solution.Their communication protocol is relatively simple and there is no encryption.Cut off the link, the drone will automatically initiate the landing procedure as a security measure. This is the operating principle of the so-called “anti-drone”: point the gun at the drone and send a powerful signal at common frequencies such as 2.4GHz and 5.8GHz.In the case of being blinded by a gun, the drone will think that it has lost the connection of the pilot and begin to return to its home.Add a GPS jammer to the mix and the drone will lose its position, drift or land immediately according to its emergency protocol.Simply put, the anti-drone gun is just a (overpriced) multi-band radio transmitter equipped with a high-gain directional antenna.   Drones are made of low reflectance materials.The challenge of radar drone detection lies in selectivity and sensitivity.Reduce the sensitivity of the radar.Fortunately, computer algorithms can distinguish threats by analyzing the patterns of flight trajectories.   Nuoanyue Technology's low-altitude slow-speed small target defense system is divided into: AUAV-portable, AUAV-fixed, and AUAV-vehicle-mounted.These three types of systems are simple to operate, can be quickly deployed, can be operated by a single person, and the equipment has a built-in large-capacity battery.The acting distance is more than 1.2 kilometers.Once the equipment is turned on, the remote control of the drone can fail, the captured images and videos cannot be returned, the GNSS navigation system loses the signal, and the contact between the drone and the remote control and even the ground end is completely cut off, so as to ensure that some important information is not leaked and avoid DRONE intrusion accidents in important facilities.  

Defense strategy: detection equipment (customized), interference equipment (customized), deception system (customized) Project introduction: An aviation airport in a certain country has its own unique operating model and safety requirements.Based on these characteristics, Shenzhen Nuoanyue has provided customized drone countermeasures equipment and strategies to ensure that the safe operation of the airport is not disturbed by drones.     Industry demand In recent years, aviation disturbances caused by civilian drones “black flying” and “flying indiscriminately” have occurred from time to time in airports around the world.Related tests have shown that a 400-gram drone can smash the windshield of a helicopter; a 2-kilogram drone can cause “serious damage” to the windshield of an airliner.Even small drones may damage the windshield of the aircraft or get involved in the engine, causing serious consequences. According to the "Regulations on the Administration of Civil Airports", it is forbidden to fly birds, kites, drones, model aircraft, and Kongming lanterns that affect flight safety in the airport clearance protection area; fireworks and firecrackers are set off.The disorderly flight and illegal use of UAVs have brought major hidden dangers to society and individuals, and the establishment of an anti-UAVS system is imminent. In view of the serious challenges posed by drone disturbances to civil airports, the Civil Aviation Administration has also actively promoted the establishment and improvement of a regulatory system, and encouraged airports to use modern scientific and technological means to improve the effectiveness of airport clearance protection.

Defense Strategy: Drone Decoy System, Radio Detection Equipment, Time Synchronization Protection Equipment. Solution Introduction: A comprehensive drone defense system not only ensures the security of the facility but also prevents information leakage, safeguarding the power plant from property damage caused by drone crashes. Industry Demand In recent years, with the continuous increase in the number of civilian drones, safety incidents caused by uncontrolled drones flying or unauthorized drone activities have been on the rise. Drone interference with the normal operation of power facilities such as power plants and transmission grids has resulted in serious consequences. Therefore, the construction of drone defense measures for power grid facilities has gradually become a priority for relevant national departments. Proposed by the Office of the National Leading Group on Counter-Terrorism, the Public Security Bureau's Administration for Public Order Management, the Anti-Terrorism Bureau, and the Bureau of Science, Technology, and Informationization of the Ministry of Public Security, the industry standard "Anti-Terrorism and Security Requirements for Power System" (GA1800.1-2021/1800.6), under the jurisdiction of the National Standardization Technical Committee for National Security Alarm Systems (SAC/TC100), was officially approved and released on April 25, 2021, and will be implemented starting from August 1, 2021. This standard, taking into account industry characteristics and practical needs, provides regulations for security and anti-terrorism measures in six areas: power grid enterprises, thermal power generation enterprises, hydropower generation enterprises, wind power generation enterprises, solar power generation enterprises, and nuclear power generation enterprises. The standard explicitly outlines the requirements for establishing anti-drone defense systems in these respective enterprise fields: The system's transmission power and frequency bands should comply with relevant national regulations. The system should be capable of automatic 24-hour operation without the need for personnel on duty. The application of the system should not cause harmful interference to surrounding important facilities. The system application should have protective measures to ensure it does not affect the time synchronization of the power system. The system should possess a detection report issued by a nationally accredited radio detection and identification institution.
