UAV detection and countermeasure system

2021-05-28

The UAV Detection and Countermeasure System" (or UAV monitoring, early warning, prevention and control system) is to measure the direction of the UAV's image transmission signal and the direction of the remote control signal in real time to realize the intrusion of unknown UAVs. And remote control detection. When the drone or remote control enters the area, an alarm is issued and the operator is warned, and the operator can choose to interfere with the equipment for forced landing or forcibly drive away the drone.

The UAV detection and countermeasure system does not limit the detection range. Generally, its detection range is equal to the available distance between the UAV and the remote control. It generally depends on the transmission power of the UAV/remote control. A single device can Independently detect a range of more than 10 kilometers; if multiple devices are set up for networking, the coverage can be expanded indefinitely. Compared with the current similar products, it has the advantages of small size, light weight, low power consumption, and multi-functions such as direction finding, monitoring and suppression, which can meet multiple purposes and realize multiple tactics. The system operating software has comprehensive functions, friendly interface, simple operation and convenient use. At the same time, the UAV detection and countermeasure system can be further optimized and perfected according to on-site operations and actual combat needs.

System Features
1. All-weather, professional drone detection software that can adapt to various environmental requirements, can identify consumer-grade drone signal characteristics and models; real-time signal acquisition and evidence playback (200MHz broadband real-time acquisition and playback domestic leading level); effective elimination The influence of WiFi signal on measurement; standard GPS/Beidou receiver for drawing maps; electronic map to mark the location of drones and remote controllers
Work uninterrupted around the clock, can be deployed in a normal manner, and can work at night, in dense fog and bad weather;

2. Ultra-long distance, which can meet the needs of wide area and unobstructed monitoring (single unit radius ≥ 10KM) 360° omnidirectional coverage, and the detection radius of a single device can reach more than 10 kilometers (depending on the drone and terrain, domestic The first omnidirectional 360° coverage and ultra-long detection distance) can capture drone image transmission and remote control flight control signals hidden among buildings and trees (the first in China that has both long-distance detection and close proximity Detection equipment); can be flexibly expanded according to user needs and the size of the area; equipment is miniaturized, portable, easy to assemble and set up on-board; it can realize mobile detection, vehicle speed ≤40KM; no detection near-field blind zone, self-adaptation Modulation receiver detection threshold; (under the same conditions, domestic first)

3. High accuracy and bandwidth, can monitor and track "drone" and "operator" at the same time. High tracking and orientation accuracy, direction finding accuracy is about 1.5°; working frequency range from 2.4GHz to 6GHz, a set of equipment can detect 2.4 at the same time The image transmission and remote controller flight control signals in the two frequency bands of GHz and 5.8GHz can be customized according to user needs in the frequency range. In addition, 2 antennas can be used to achieve full coverage from 30MHz to 6GHz; (16U processing host, which can be expanded arbitrarily Frequency band to be detected) Real-time measurement of radio frequency signals of UAV, remote control, etc.; 40MHz acquisition bandwidth supports real-time spectrum analysis and frequency hopping signal monitoring; it can monitor and track UAV and flight control signals at the same time, and the detection speed is fast , It has the function of discovering and positioning as soon as the remote control is turned on, which is convenient for early warning and disposal;

4. Passive, low power consumption, can prevent passive radar from being detected, no radiation, hidden in work, not easy to be found, and will not cause any electronic interference to other boot devices during work. No radiation, long-term use will not cause any adverse effects on the human body; it is quick to set up and ready to use; the drone detection and countermeasure system has low power consumption, <100W/h, and can be extended with an external battery and power supply to extend on-site operation ;

5. Strong scalability
The detection frequency band is extensible. The current equipment can detect 2.4GHz, 5.8GHz and 5GHz. When a new UAV measurement and control frequency band appears, the detection host can be quickly upgraded and perfected;

The signal is scalable and can identify common drones on the market. When new drone brands and series appear, the existing database can be quickly updated; the drone detection and countermeasure system is scalable and can be integrated For radar, photoelectric and interference control systems, the positioning accuracy can accurately guide photoelectric equipment to implement tracking and precise confirmation, and then guide the interference equipment to implement effective interference; the drone detection and countermeasure system is scalable and has professional drone detection With the software, multiple devices can be networked according to user needs to form a UAV detection situation, add a list of black and white UAVs, and establish a dedicated command center.
