The drone anti-jamming systems and anti-spoof technology protect against interference, jamming, and spoofing of the UAVs. To protect their security, countries are beginning to research drone anti-jamming systems, also known as drone strike weapons. The anti-jam and anti-spoof technology protects against interference, jamming and spoofing. A drone strike weapon is a drone attack weapon that can attack and destroy enemy drones. So what is so unique about this amazing system? According to scientists, the main components of a drone are wings, propellers, batteries, electronic controls, and other equipment. The systems of these drones are maneuvered by remote control. Therefore, drones must be aggressive to be used in drone combat. Since drones are affected by terrain, obstacles, and weather when striking targets remotely, they need to have more than one eye to get optimal strikes and thus increase hit rates. In addition, it should be equipped with rockets and even cruise missiles specifically designed to target small and light-fixed or moving targets. The biggest advantage of drones is their flexibility, speed, and stealth. Suppose the drone is loaded with various kinds of explosives and uses GPS/GNSS to receive signals. In that case, it can find out the pre-buried detonation lines to carry out continuous bombing, which is enough to paralyze any fortifications and important facilities and give strong killings. At the same time, relevant data is collected and transmitted back to the command room to prepare for the next decision.

Contact: info@ctrfantennasinc.com (+86)13412239096 There are many modified UAV products in the current market, for example, replacing ordinary cameras with radar, infrared thermal anti-jamming sensors, depth camera arrays, ultrasonic detectors, etc., which increases stability and reduces fuel consumption. In the future, drones will serve mankind better. What is the principle of drone anti-jamming systems? A drone is an aerial vehicle that has been widely used in various fields, such as aerial photography, agriculture, logistics, rescue, and so on, due to its flexibility and efficiency. As the number of drones continues to increase, some illegal uses have begun to appear, such as the invasion of privacy or the use of drones for malicious purposes. Therefore, drone anti-jamming systems are becoming more and more important. Drone anti-jamming refers to the use of various means to stop the illegal use of drones or control drones for specific operations. It mainly includes the following principles. 1. Electromagnetic jamming principle By transmitting electromagnetic signals to the drone, it interferes with its communication or navigation system, causing it to lose control or be unable to fly correctly. This method usually uses electronic jammers or electromagnetic wave scramblers. 2. Optical jamming principle By emitting light beams to the UAV, it interferes with its visual system, making it unable to recognize the target correctly or fly normally. This method usually uses laser beams or photoelectric jammers. 3. Mechanical Jamming Principle By launching high-speed flying objects at the UAV, the UAV will be hit, causing it to lose balance or fall. This method usually uses UAV interceptors or UAV anchors. 4. Thermal Jamming Principle Launching high or low-temperature substances at the drone, interferes with its power system or navigation system, making it unable to fly correctly. This method usually uses rockets or cryogenics. It is important to note that the drone anti-jamming systems principle is not just a single tactic, but usually requires a combination of tactics to achieve the best anti-jamming results. At the same time, when conducting drone anti-jamming systems, it is also necessary to follow the relevant laws and regulations to avoid unnecessary legal disputes.

Drone anti-jamming systems for prison application Drones continue to be one of the most destructive technologies of the last decade. As they have entered the mainstream public eye, people have begun to utilize the technology and misuse drones. Prisons face the challenge of smugglers using drones to transport drugs, weapons, cell phones, and other contraband onto facility grounds. Prisons are secure units where people are restricted from committing crimes. Communication and interaction with the outside world is limited. Certain everyday items such as cell phones, tobacco, and cigarettes are banned or restricted, and other items such as drugs, razors, etc. are prohibited. What can prisons do when faced with these types of problems? There are options for drone defense systems that work 24/7. Prisons can integrate a drone anti-jamming system into their area-based alert system for consistent and complete surveillance of their perimeter, airspace, and centralized facilities. Its alarms provide advanced warnings of drone activity and can be configured to automatically disrupt drones entering a specified perimeter. The Drone Anti-jamming Systems are installed near external and internal perimeters that you can maintain remotely. They contain a database of drone acoustic signatures typically used for smuggling and links to a browser-based interface that lets you view local acoustic activity in real-time. As soon as a drone is detected, the Anti-jamming Systems send out an immediate alert via text message, email, or your existing alarm system, and can automatically disrupt an unauthorized drone within seconds.

Contact: info@ctrfantennasinc.com (+86)13412239096 jamming range; the jamming signal objects include uplink remote control signals, downlink telemetry, and map transmission signals of UAVs working in 2.4GHz, 5.8GHz, 1.5GHz, 433MHz, 868MHz, and 915MHz frequency bands. It can also add 315MHz, 1.2GHz, 1.4GHz, 1.8GHz, 2.1GHz, 2.3GHz, 2.6GHz, 3.5GHz, 5.15GHz, and so on. 3.Drone anti-jamming system working mode and working mode The drone anti-jamming systems adopt a fully automated, intelligent, 7x24h unattended working mode. Specifically can be set to use one of the four working modes. Full-automatic mode (detection and jamming without any manual participation, as the main working mode); Semi-automatic mode (automatic detection and identification, but inquiries before the jamming strike, manually determined by the implementation of the jamming strike); Clearance mode (uninterrupted continuous scanning jamming of the entire perimeter or designated angle airspace, which can effectively prevent drones working with radio from taking off from and flying into no-fly zones, defense zones, or alert zones); Manual mode (detection, identification, and jamming strikes are all operated manually, and this mode is mainly implemented by technical experts); 4. Scalability and openness The drone anti-jamming systems have a good scalability, according to the needs of the late addition of equipment to achieve stronger functions. (For example, the ability to combat interference in the 130-3000MHz frequency band other than 2.4GHz/5.8GHz; optical surveillance, radar detection, and other monitoring methods: the ability to monitor and discover other types of unmanned aerial vehicles that do not use radio). The drone anti-jamming systems have a good openness and can interface with other systems of the user according to their needs and push important information to them. How to anti-jamming drones?

Contact: info@ctrfantennasinc.com (+86)13412239096 At present, drone anti-jamming systems mainly use four methods, of which, interference blocking is the most important means, by interfering with the communication or hardware of the drone, it can force the drone to return to the flight automatically or land automatically. The other three methods are deception control, interception capture, and direct destruction. 1.Interference blocking (1) Electromagnetic jamming Electromagnetic jamming can effectively block the communication between the UAV and the control station, cut off the UAV's remote control signals, as well as digital and graphic signals, and achieve the purpose of forcing the UAV to land or drive it away. Electromagnetic jamming is directional or omni-directional jamming, effectively dealing with multiple UAVs within the action distance. (2) Navigation signal jamming The UAV generally utilizes the satellite navigation and positioning system to locate itself, and the implementation of navigation signal jamming can cause the UAV to be unable to accurately locate itself, thus affecting the UAV's flight control system and restricting the UAV's flight. (3) Acoustic wave jamming This is an expensive jamming method. The UAV maintains its balance through the feedback information of the gyroscope and the control system. Control system to maintain its balance. Acoustic jamming can send out sound waves with the same frequency as that of the gyroscope, causing the drone to experience the gyroscope, causing it to resonate, and preventing the gyroscope on the UAV from working properly. 2.Deception control

Contact: info@ctrfantennasinc.com (+86)13412239096 (1) Navigation signal deception The launch of false navigation satellite signals to “deceive and confuse” the UAV, so that the UAV mistakenly believes that its target is a false position preset by the system. Since the satellite navigation signals received by the UAV are weak, the system only needs a small amount of transmit power to realize the deception effect on the UAV. (2) Radio signal hijacking This method involves first cracking the communication protocol of the drone signal and then sending a control signal with a stronger signal to the drone, thus controlling the drone. 3.Interception and Capture Intercepting and capturing from the ground or the air, mainly using launching guns to shoot capture nets, or employing large drones to capture small drones, in addition, there are also training eagles to capture drones and bring them to designated areas. 4.Direct Destruction Missiles, laser weapons, microwave weapons, etc. are all capable of attacking drones. However, these methods have more various constraints and can also lead to the crash of the drone. Therefore, direct destruction is suitable for use in suburban and field environments and is not suitable for urban environments.
