Uav communication jamming

This type of UAV has a strong attack capability, which can effectively attack enemy armored vehicles and reinforce positions and other targets. Russia is still actively developing new models, and by using lighter coils and longer cables, the flight performance and operational radius of UAVs are further improved to meet the needs of more complex battlefields. Ukraine's Khyzak REBOFF "Raptor Reboff" is also a prominent fiber-guided FPV UAV. It pays attention to the combination of flexibility and reconnaissance ability in design, and can fly in low-altitude complex environment, which provides an important battlefield situation awareness means for the Ukrainian army. When carrying out the task, it can rely on the advantages of optical fiber communication to quickly and accurately transmit the obtained information back to the ground control station. For fiber-guided FPV UAV, countries are also actively exploring effective countermeasures. As an important part of air defense system, radar can scan the airspace in all directions. By transmitting electromagnetic waves and receiving reflected waves, the radar can accurately obtain key data such as the position, speed and flight direction of the UAV, and provide accurate target information for subsequent interception actions. For example, the Magyar Birds Brigade in Ukraine claims that they have developed a system using mobile radar, which can give early warning to FPV drones several kilometers away, and once detected, they can take corresponding countermeasures. Photoelectric identification equipment is also one of the important countermeasures. This kind of equipment uses technologies such as optical camera and infrared thermal imager to identify and confirm air targets. The optical camera can shoot the visible image of the target, and judge whether the target is an optical fiber-guided FPV drone through image analysis technology. The infrared thermal imager can detect the infrared radiation characteristics of the target, and can accurately identify the position of the drone even at night or in low visibility environment, thus improving the detection and identification ability of the drone. In addition, although the fiber-guided UAV itself has strong resistance to traditional electromagnetic interference, it can still destroy its communication by interfering with the radio link of the repeater it may use, such as Wi-Fi or data link. By analyzing the communication frequency band of UAV and using high-power electronic jamming equipment to transmit high-intensity jamming signals to this frequency band, the communication link between UAV and operator may be interrupted, delayed or have data errors, resulting in the UAV losing effective control. Laser weapon has become a powerful weapon against UAV because of its fast and accurate strike characteristics. The laser beam travels at the speed of light, almost without aiming time, and can attack the drone in an instant. Once the target is locked, the laser weapon can focus the high-energy laser beam on the UAV in a short time, so that the key components of the UAV, such as batteries and electronic equipment, are damaged due to overheating, thus realizing the rapid and accurate destruction of the UAV. In addition, there are many other countermeasures. For example, it is a more traditional but effective way to deploy an air interception network. By setting an interception network in key areas, when the drone flies by, the interception network can entangle the optical fiber of the drone and make it lose communication and control, thus achieving the purpose of interception. In addition, strong light jammer can be used to blind the camera of UAV, which can make it impossible to obtain clear images and affect its reconnaissance and attack ability. Or deploy smoke to cover the battlefield, reduce the visibility of the drone and interfere with the work of its optical reconnaissance equipment. Based on open source information, the author searched and sorted out the typical system of fiber-guided FPV UAV and the operational application cases of this kind of UAV. According to the corresponding cases, the operational process, operational style, typical operational scenarios and tactical application strategies of fiber-guided FPV UAV were analyzed in detail. In addition, countermeasures for fiber-guided FPV UAV were put forward from three aspects: civil air defense, physical defense and technical defense. At the end of the report, the technical challenges and future development trends of fiber-guided FPV UAV were discussed.
