Fixed Drone Detector With Full-Band Coverage And Direction Finding Accuracy Of ≤3°
Introduction
This high-precision detection system integrates full-band RF spectrum monitoring (70MHz–6GHz) and multi-sensor fusion to achieve comprehensive drone identification and localization across critical airspace. Combining multi-static interferometry antennas , it delivers 360° azimuth coverage and vertical scanning (-30° to +70°), enabling ≤3° directional accuracy for UAVs as small as 0.01m² RCS. The system employs AI-driven signal fingerprinting to decode drone protocols (e.g., DJI OcuSync, Autel AES), while correlating radar micro-Doppler signatures with optical thermal imaging data to suppress false alarms from birds or environmental clutter with 98.5% reliability Operational capabilities include adaptive full-band jamming targeting GNSS (GPS L1/L2/L5) and control links (2.4GHz/5.8GHz), synchronized with cognitive waveform synthesis to disrupt unauthorized drones while preserving authorized communications. A neuromorphic processing core leverages spiking neural networks (SNNs) to analyze 20TB/hour of multi-sensor data in real time, achieving <1.5-second threat classification and automated countermeasure activation.

|
Drone detection |
• Detection spectrum bandwidth: 70 MHZ - 6GHZ, detection focus on the 433Mhz, 868Mhz, 915Mhz, 2.4Ghz, 5.2Ghz, 5.8Ghz • FPV Detection:300Mhz-6.2Ghz Analog Signal of FPV Drones • Simultaneous screening number of UAV: ≧150pcs • The lowest detection height: ≤0 meters • Detection rate: ≧99.99 %s |
|
Drones Location |
For UAVs with Remote ID (China GB42590-2023, US ASTM F3411-22a, EU ASD-STAN PrEN4709-002) and Drone ID (such as DJI Mavic2, Mavic3, air3s, Matrice4, etc., some require network decryption), it can parse detailed information such as drone location and pilot location. |
|
White and Blacklist |
• The Systemcan identify ≧ 400 different model UAV including DJI series drones,and it has the autonomous learning ability. • The Systemcan carry on the accurate identification of target, in-depth analysis of UAV signal, the identification of unique ID, and the black and whitelist to distinguish. • Whitelist and a blacklist can be set for different targets of the same position, same frequency band, same manufacturer, same type of UAV respectively. |
|
Defensive Interference |
PS The Systemhas interference capabilities of 900MHz, 433Mhz; 1.5ghz, 2.4ghz, 5.8ghz; 5.2Ghz and other customized frequency bands, and covers most of the UAV communication available in market. |
|
Remote OAM |
After turning on the fully self-movable defense, it can enter unattended mode, detect, and strike autonomously. And a variety of OAM features are available when used with the remote server, including firmware updating, resetting, status inquiry, self-testing, parameter configuration, and more. |
|
GPS |
The Systemcan detect its current position using its built-in GPS. |
|
Networking |
The Systemcan network multiple devices through the cloud server, observe the online/abnormal status of each device, and control the device remotely through the mobile terminal (mobile phone IPAD), including but not limited to viewing the operating interface of the device system, receiving alarm information, viewing the black and whitelist, and turning on defense functions. |
|
Data security |
Use certificate management and data encryption between the equipment and server to ensure data reliability and security. |
