Advanced fixed anti-drone direction finding technology for use in the security field.

I. Real-time UAV Signal Detection and PositioningAdvanced fixed-position anti-UAV direction-finding technology utilizes a high-sensitivity radio frequency receiver module and intelligent signal processing algorithms to achieve real-time detection and precise positioning of UAV communication signals. The system can automatically capture UAV control link and image transmission signals in complex electromagnetic environments and quickly calculate the approximate location and distance of the UAV and its control terminal through multi-point direction finding and cross-positioning algorithms. This technology can issue an early warning the moment a UAV enters the monitored area, providing security personnel with accurate target location information. Through continuous data acquisition and analysis, the system can also dynamically track flight trajectories, thereby achieving 24/7 real-time monitoring of suspicious UAV activities and significantly improving airspace security capabilities for airports, prisons, government agencies, and large event venues.

III. 360° Omnidirectional UAV Monitoring CoverageThis system adopts a multi-array antenna and omnidirectional receiving structure design, enabling 360° UAV signal monitoring coverage without blind spots. Through a multi-channel parallel processing architecture, the device can simultaneously receive radio signals from different directions and quickly analyze and determine the target signal. Combined with a distributed deployment scheme, multiple devices can build a regional airspace monitoring network, further expanding coverage and improving positioning accuracy. The system can continuously monitor low-flying micro and small drones, maintaining stable signal acquisition capabilities even in densely built-up or complex environments, establishing a reliable low-altitude security barrier for critical areas.

IV. All-Weather Drone Monitoring SystemThe advanced fixed anti-drone direction finding equipment is designed for all-weather operation and can work stably under various climatic conditions. The equipment features industrial-grade hardware and a high-protection-level shell, resisting the effects of high and low temperatures, strong winds, rain, snow, and dust. The system supports 24-hour continuous operation and is equipped with remote management and automatic diagnostic functions. Maintenance personnel can view equipment status and monitoring data in real time through a network platform. Simultaneously, the system can also be linked with security platforms, radar systems, or video surveillance systems to form a multi-layered low-altitude protection system, providing continuous and reliable airspace security for critical infrastructure.

V. Multi-Band Drone Signal Recognition CapabilityThis technology possesses powerful multi-band signal recognition capabilities, enabling comprehensive monitoring and analysis of commonly used communication frequency bands for mainstream civilian drones, including 433MHz, 900MHz, 1.2GHz, 2.4GHz, and 5.8GHz. The system utilizes a built-in signal feature database and machine learning algorithms to identify and classify the communication protocols and modulation characteristics of drones from different brands and models. When abnormal or unauthorized drone signals are detected, the platform can quickly mark the target and generate alarm information. Furthermore, the system supports continuous updates to the signal feature database to adapt to the ever-changing trends in drone technology, thereby maintaining long-term stable identification and monitoring capabilities.
