Fixed-position anti-drone system with precise direction finding capabilities

This fixed anti-drone system possesses high-precision direction-finding capabilities, enabling simultaneous passive monitoring and direction determination of both the drone's control link and image transmission link. The system utilizes multi-channel parallel reception and intelligent signal recognition algorithms, automatically distinguishing different types of drone signals in complex electromagnetic environments, achieving synchronous capture and independent direction finding of control and image transmission signals. Through the fusion analysis of dual-link information, the system can more accurately pinpoint the drone's location, providing reliable data support for subsequent early warning, tracking, and countermeasures.

The system covers the mainstream drone communication frequency bands in the 400MHz–6GHz range, effectively monitoring the control and image transmission signals used by common consumer, industrial, and some customized drones. Whether it's common frequency bands such as 2.4GHz and 5.8GHz, or lower-frequency dedicated communication bands, the system can achieve continuous scanning and precise direction finding, ensuring a high detection rate and low false alarm rate for target drones.

This anti-drone system supports 7×24 hour continuous and stable operation, possessing comprehensive self-checking, self-recovery, and remote maintenance capabilities, making it suitable for long-term fixed deployment. The system can automatically complete signal monitoring, alarm reporting, and data storage under unattended conditions, significantly reducing manual monitoring costs and meeting the all-weather protection needs of airports, critical facilities, border defenses, and important event venues.

The system supports both single-site independent deployment and multi-site networked collaborative deployment. The single-site mode is suitable for rapid protection in small to medium-sized areas, while multi-site deployment enables the fusion of direction-finding data and cross-location through the network, significantly improving positioning accuracy and coverage, meeting the anti-drone application needs in large areas and complex scenarios.
