Operational principle
The system equipment does not need to actively transmit signals. By passively receiving all kinds of UAV signals in the control area, the detection and identification of the UAV in the area can be realized, and the UAV can be accurately located through T DOA wireless positioning technology. The system synchronously transmits the detection and location information to the control platform. Users can obtain the black flight situation according to the interface. Through manual operation or automatic decision through the interface, the linkage countermeasure equipment automatically or manually launch the interference suppression signal, effectively cut off the channel charge or navigation link of the UAV, and drive away and land the UAV.

System function description
1. Real-time spectrum monitoring: The system can monitor and display the wireless signal spectrum received by the detection equipment in real time, and supports the simultaneous display of energy waterfall map and spectrum map; can display no less than 8 different sub-bands;
2. Frequency hopping tracking: The system has the function of UAV frequency hopping signal tracking. When the working frequency band of the UAV detected by the detection equipment changes, the platform can automatically track the UAV signal after the working frequency band changes;
3. Black and white list: The system has the function of black and white list, which can distinguish between cooperative UAV and non-cooperative UAV, and the platform does not alarm when the cooperative UAV is detected;
4. GIS electronic map: The system has GIS (electronic map) function, support online or offline GIS system, support online or offline electronic map. Support the loading of Autonavi, Baidu, Tencent and other electronic maps;
5. Multi-trajectory tracking: The system has the function of multi-target trajectory tracking. When the detection equipment detects and positions the multiple sorties at the same time, the flight trajectory of the UAV is displayed;
6. Alarm function: The system has alarm function. When the detection equipment detects that the UAV enters the control area, the platform can provide information, icon, sound and light alarm prompts;
7. SMS alarm: The system has the function of SMS push: when the detection equipment detects the UAV, the platform can send SMS to push the UAV intrusion information to the preset mobile phone number;
8. Multi-level defense: The system has the function of setting the defense range. When the UAV is detected in the defense area, the system will not alarm the UAV outside the defense area;
9. Unattended: With the unattended function, the detection equipment controlled by the platform can coordinate the UAV to automatically transmit interference signals to drive away or crash land the UAV;
10. Log recording: With the function of UAV intrusion logging, it can replay the detected UAV intrusion log through the platform;
11. Free networking: The system can conduct networking communication through unwired / wired mode, and the platform conducts free networking for multiple sets of detection equipment to realize continuous control of large areas.
System characteristics
1) Wide monitoring frequency band range: with the full frequency spectrum real-time spectrum monitoring function, can monitor the frequency band range of 100 MHz ~ 6 GHz;
2) High positioning accuracy: the system is based on TDOA arrival time difference positioning technology, and the positioning error reaches the order of 10 meters, which can help realize fine low-altitude airspace management;
3) Support the positioning and tracking of UAV frequency hopping signal, and can track and locate multiple targets at the same time;
4) Support for multi-point grid networking, to achieve a large area without blind spot coverage;
5) Support 7 * 24 hours unattended, inspection and combat integration, multi-level alert, layered defense, precise control;
6) No electromagnetic radiation influence, environment-friendly, less application scenario restrictions. The detection unit is small and portable, suitable for fixed, mobile and fast cloth stations;
7) The system supports online or offline GIS (electronic map) system, and supports Google, Bing, Autonavi and other electronic maps;
8) The system can freely network multiple sets of detection equipment and counter equipment through the control software, and control them separately. The unique system fusion algorithm supports the same system to control multiple groups of management and control equipment, which is intelligently optimized by the system to realize seamless control of large areas and achieve the optimal UAV control effect;
9) The system adopts platform design, and many different modules adopt unified data interface for facilitate expansion. The expansion module includes a series of modules, such as radar detection equipment, omnidirectional / directional counter equipment, ADS-B receiving equipment, optical forensic tracking equipment, and GPS decoy equipment, which are suitable for combined use in different scenarios.
