In recent years, the market of drones has developed rapidly,the popularity of civilian drones has become higher and higher,especially “black fly” The supervision of drones is still in the development stage. It is known that there have been many incidents of illegal flight, photographing and delivery of illegal items in the restricted areas , the safety of low-altitude has been seriously threatened.
The continuous occurrence of the “black fly” incident of the drone has put a hard situation on the low-altitude security management system, and it is necessary to fundamentally change the status of the low-altitude security technology and the relatively lagging under the new threat. All-round, all-weather monitoring and control is the goal of low-altitude security. Therefore, it is necessary to build a stereoscopic and all-directions detection and jammer system for drones from the ground to the low altitude.
The UAV drone bocker system in low-altitude needs to meet the following requirements:
- Detect and find the drone
The system can detect and find the UAVs , and update the target dynamically to determine whether it is a dangerous target.
- Effective counter against the target
The drone jammer device can effectively counter the threat target, and can achieve the effect of landing the target in situ or catching the drone.or bock the RF (radio frequency ) and make the drone out of control or leaving the area.
- Automation, unattended.
When there is no personnel to be on duty, the drone jammer system can automatically complete the entire workflow from detection to counter-attack, with full-day protection.
- The anti-uav blocker system is mature and stable
The system should be easy to deploy, automate, and easy to operate. The system equipment should be mature and stable, with high reliability. It has a wealth of application cases and can be deployed in a long-term fixed deployment to perform low-altitude security tasks.
The Drone UAV Jammer Block system working process
In the radar warning area,front-end real-time monitoring, omnidirectional receivingand and processing of the electromagnetic signal. Once the drone signal is identified, the information is compared firstly, and the black and white list in the system is compared to determine whether the target is a “black fly” drone. Once it is determined that it is a “black fly” drone, the front-end immediately reports data to the control center through the network. The control center that based on the terminal software to display the target orientation and flying information and activates the intrusion alarm, the warning light flashes, The patrol person who take the drone jammer gun will also receive the alram singal from the control center, and search the “black fly” drone, it is a fixed and mobile network capture system. Capture the “Black Flying” drone pilot based on the detected information,the drone jammer system to interfer and blcok the “black flying” drone,and the turn-table interference equipment counter the “black flying” drone that entering the long-distance area. Omni-directional interference is handled by the “Black Flying” drone in the 1km to 2km area. After the anti-drone working is completed, the front-end of the control center to confirm the reports result.
System composition and configuration
The anti-UAV system is composed of detection subsystem, interference disposal subsystem, command and control subsystem and communication subsystem. The detection subsystem mainly detects and locates intrusive targets and gives timely alarms; the interference disposal subsystem effectively counteracts the detected UAV targets; and the command and control subsystem is integrated. The brain of the system can collect data, display situation and command and control with the front end, and the communication subsystem is the carrier of data transmission of the system.
The detection subsystem of this scheme is a set of spectrum detection equipment.
The jamming disposal subsystem consists of a set of omnidirectional jamming equipment, a set of turntable jamming equipment and a set of networked portable UAV detection jamming gun.
Turntable jamming equipment mainly manages and controls long-range threatening targets and tracks them dynamically in real time. The longest distance can reach 3 km.
The main control radius of omnidirectional interference is from 1 km to 2 km, and the diameter is from 2 km to 4 km.
The networked portable UAV detection jamming gun can simultaneously display and jam the target detection information of UAV, and the working distance can reach 1.5 km.
The command and control subsystem is equipped with a command and control management platform, which can be arranged in the duty room. The communication subsystem adopts optical fiber network/wired network transmission mode.
