1. Detection and Positioning: Utilizing passive spectrum sensing technology operating across 20MHz-6GHz frequency ranges, the system employs multi-array directional antennas to capture wireless signals from drones within its detection zone. Through radio protocol analysis, it automatically identifies critical drone parameters including geographic coordinates, altitude, speed, heading, model type, serial numbers (SN), and takeoff points, which are then transmitted to the control platform for real-time visualization and data processing. The system demodulates physical layer and link layer data to extract unique identifiers for precise identification, enabling features like frequency discrimination and black/white list management. With high-precision frame synchronization, it captures signal timestamps, phase information, and coherent power measurements for positioning applications. The detection range extends up to 15km, capable of simultaneously monitoring over 60 drones, covering more than 95% of commercially available drone models.
2. Interference Handling: Utilizing high-speed frequency scanning technology, electromagnetic interference is employed to disrupt the navigation, remote control, and video transmission signals of drones. This forces the drones to return or land, while enabling precise targeting of specific drones. The omnidirectional interference range reaches up to 3km. Depending on application environments and requirements, different antenna configurations can be deployed to achieve optimal cost-performance ratios while meeting regional coverage needs.
3. Control Platform: Built on SOA architecture, this system provides multi-access modes including web and mobile applications, enabling centralized management of over 20+ UAV detection and countermeasure systems. It features real-time electronic map display with device locators, UAV tracking markers, remote controller position indicators, and azimuth guidance. The platform supports operational status monitoring, data logging and retrieval, spectrum analysis, audio-visual alarms, unmanned operation, black/whitelist management, manual interference verification, manual-automatic switching, and data analytics. Furthermore, it allows future integration with additional UAV countermeasure systems such as radar, electro-optical, and decoy devices.
4. Vehicle-mounted accessories: mounting brackets, distribution boxes, onboard batteries, UPS, and generators. The battery monitoring system operates continuously for 12 hours and withstands 2 hours of interference. It supports AC220V continuous operation.
5. Fixed installation components: pole supports, concrete bases, distribution boxes, and lightning protection systems are connected to AC220V for continuous operation.
6. Temporary deployment components: tripod, portable power supply, deploy and use anytime, anywhere.
