UAV Countermeasures: Trends in Counter-UAV Technology
In recent years, drones have developed rapidly, illegal acts of "black flying" have occurred frequently, and safety problems have also increased.
Before the Spring Festival in 2021, a set of drone jammer system integrating detection and countermeasures was successfully tested at a railway station in Guangdong and ensured the low-altitude safety of the railway station during the Spring Festival. big effect.
"We developed an integrated surveillance system for drones. One device can monitor drones in real time, force landing and drive away, monitor drone remote controllers, and even be used as radio monitoring equipment."
The system uses passive radio monitoring to receive UAV signals. The receiving frequency range is 10MHz to 6000MHz, and the real-time bandwidth is 480MHz. It can search, detect and alarm UAV image transmission and measurement and control signals in real time. And the parameter measurement of the measurement and control signal, the single-station direction finding, and the rough ranging functions. The biggest feature of the system is that it does not rely on the database. It can learn the signal characteristics of UAVs independently, and identify unknowns including all industrial UAVs. At the same time, the device can also be equipped with an identification chip to realize the black and white list function. Combined with the identification database, the drone model and manufacturer can be identified, and the drone can be positioned and continuously tracked.
He Weiwei, technical engineer of the integrated system of drone detection and countermeasures, said: "Our equipment can not only be used as a radio monitoring receiver, but also can be used in conjunction with a navigation deception system, which can deceive the drone to a designated safe location. Make a landing." Nowadays, drones are seen in many fields and life scenes, but "black flying" and "chaotic flying" also occur from time to time, and the new drones are more intelligent and have human faces. Functions such as identification, tracking and positioning, and precise strikes seriously affect social and public security. Liao Shoufeng, chairman of Shenzhen Wufeng Technology Co., Ltd., said: "There have been many drone "black flying" incidents between 2016 and 2020, and even in 2021, the first year of the year, there have been many illegal flights. There have been incidents in which drones have been punished, such as the collision between the subway and drones in Chongqing, which has affected the traffic track, and this disturbance has seriously interfered with the safety of civil aviation flight.”
This integrated detection and countermeasure anti-UAV system has successfully broken through the integrated technologies of detection, identification, jamming and induction of UAV countermeasures, filling the role of our country's efforts to detect and control "black flying" unmanned aerial vehicles. blank in machine technology.
The system equipment can be set up unattended, so that all-weather, full-time work can be done to better maintain low-altitude public safety.
With the rapid development of drone technology in recent years, anti-drone technology has also emerged as the times require. The integrated detection and countermeasure equipment of Shenzhen Wufeng Technology Co., Ltd. is also the first complete civilian UAV countermeasure system with independent intellectual property rights in China. Won the first place in the "Invisible Volley" fixed-point forced landing in 2019. The UAV countermeasure system can be widely used in institutions, national defense and military industries, aviation airports, oil refining and storage depots, stadiums and industrial facilities, etc., and realizes passive detection, no dead ends and unattended operations, becoming a tool to ensure public safety. "Sharp tool".
