BF-W550 Drone Detection and Countermeasure System

Overview of drone detection and countermeasure equipment
The drone direction-finding, positioning and countermeasure equipment is an integrated system for drone detection and early warning, target identification, direction-finding, positioning, interference disposal and management and control. It can be equipped with vehicle-mounted components, fixed-installation components and temporary deployment components, and is flexible in application and suitable for multiple scenarios.

1. Detection and positioning: Passive spectrum detection is adopted, with a detection frequency of 20MHz-6GHz. The radio signals of drones in the detection area are received through multi-array direction-finding positioning antennas. The radio protocol analysis technology is used to automatically detect and identify the latitude and longitude coordinate information, altitude, speed, direction, model, SN code, take-off point and other information of common drones, and report to the control platform for real-time display and data processing. Demodulate the physical layer and link layer information, extract the unique identification of the drone for accurate identification of the drone, so as to realize the functions of same-frequency distinction, black and white list, etc.; high-precision synchronous frame structure, obtain signal frame timestamp, phase and coherent power, for orientation and positioning system; the detection distance is up to 15km; detect more than 60 drones at the same time, covering more than 95% of drones on the market.
2. Interference disposal: High-speed digital frequency scanning technology is used to interfere with the navigation, remote control, and image transmission communication signals of drones through electromagnetic interference, thereby forcing the drones to return or land, and can achieve precise interference to designated drones; the omnidirectional interference range can reach 1.5-2km, and different antenna forms can be configured according to the application environment and needs to achieve the most economical and optimal performance to meet regional coverage requirements.
3. Management and control platform: Based on SOA architecture, it provides multiple access methods such as web pages and APPs, and can realize the access and management control of more than 20 sets of drone detection and countermeasure equipment. It has electronic map display, equipment positioning icon, drone positioning icon, remote control positioning icon, direction pointing and other displays, operation status monitoring, data recording and query, spectrum diagram, sound and light alarm, unattended, black and white list, manual interference secondary verification, manual automatic switching, data analysis and other functions, and supports subsequent expansion to access other drone countermeasure systems or equipment, including radar, optoelectronics, decoys, etc.
4. Vehicle-mounted supporting components: vehicle-mounted bracket, distribution box, vehicle-mounted battery, UPS, generator, battery working time detection continuous working 12h, interference 2h. Support AC220V connection for continuous working.
5. Fixed installation components: Pole bracket, cement base, distribution box, lightning protection, etc. are connected to AC220V for continuous operation.
6. Temporary control components: tripod, mobile power supply, deployment and use anytime and anywhere.

Product composition
The product mainly consists of a detection host, an interference host, a power cord, a network cable and a laptop computer, as shown in the following table:

Main functions and features
1. Passive detection: It only passively receives without emitting any electromagnetic signals, and detects the spontaneous signals of drones. It can detect the brand, model, frequency and other information of illegal drones. It is not affected by rain, snow or fog, and has all-weather, all-day, 360° detection.
2. Unmanned operation: After turning on unmanned operation, efficient drone defense management can be achieved. After detecting illegal drones, the control platform will automatically start interference disposal, and the interference duration and cycle duration can be set.
3. Direction finding function: High-precision lateral positioning technology and protocol cracking technology are used to achieve accurate direction finding of illegal drones. The direction finding accuracy of mainstream drones is less than 5m.
4. UAV and pilot positioning: It can locate the location information of DJI series UAVs and remote controllers, and display the UAV's latitude and longitude coordinate information, direction information, distance information, speed, altitude, etc. in real time.
5. Black and white list: Identify the unique serial number of the drone, mark it on the white list with one click, add the legally flying drone to the white list, and the system will not generate an alarm when the drone flies into the protection area.
6. Complete model library: The system can identify and detect most models of common brands of drones such as DJI, Dotcom, Parrot, Dahua, Haoxiang, 3DR, Xiaomi, Ehang, Zero, Yidian, as well as self-made flying drones, WiFi drones, etc. on the market;
7. Ultra-long-distance warning: In an environment without interference or obstruction, the detection distance of the multi-array side-positioning antenna can reach up to 15km; measures can be taken in advance. Covering more than 95% of drones on the market.
8. Precision strike: For designated aircraft types, the drone communication protocol can be cracked, the drone frequency modulation signal can be detected, and narrow-band interference can be used to accurately interfere with the drone.
9. Broadband strike: Using high-speed digital frequency sweep technology, high-power radio frequency amplification technology, and omnidirectional antennas, it can simultaneously interfere with multiple drones in multiple directions, forcing drones to return or land.
10. Data statistics and analysis: Provide detection and countermeasure data statistics, display, and analysis, including drone flight data, time, list, historical trajectory, alarm status and other statistical information.
11. Electronic map: support online and offline map updates
12. Mobile operation: The equipment can operate normally under high-speed moving state.
13. Database upgrade: Supports remote free upgrades. The model database will be updated from time to time according to changes in the drone industry.
