10km Long-Range RF Drone Detector System 300MHz-6GHz Spectrum Analyzer Anti-UAV Defense Solution

This advanced RF drone detection system employs cognitive radio protocol reverse parsing technology, utilizing radio spectrum sensing similar to virus feature extraction in antivirus software. The system extracts UAV communication signals (primarily remote control and image transmission signals) from background noise and conducts in-depth reverse parsing.

Through offline analysis of UAV communication protocols and feature extraction (electronic fingerprint ID), including channel distribution, modulation schemes, coding schemes, pilot sequences, synchronization sequences, and link layer structures, the system forms a comprehensive UAV detection database. Real-time matching occurs in actual radio environments, applying features to real-time detection (fast feature matching recognition) and precise strike capabilities (distinguishing different UAVs for targeted action).

The system's technical features include significantly superior detection sensitivity, signal-to-noise ratio, and accuracy compared to traditional spectral energy sensing methods. It demodulates physical layer and link layer information to extract unique drone identification (electronic fingerprint), enabling precise drone identification, same-frequency discrimination, and black/white list functionality.

Additional capabilities include identifying weak points in frame structures (such as pilot signals for channel estimation and synchronous reference signals for frame synchronization) for accurate interference effects. The high-precision synchronous frame structure acquires signal frame timestamps, phase, and coherent power for orientation and positioning systems. For certain communication protocols, the system can synchronously transmit fake physical layer frame structures to mislead target drones (achieving drone takeover).

Main functions include passive detection (no electromagnetic signal emission), accurate direction finding with ≤10° moving and ≤3° hovering precision, precise identification of different drones within same brand/model/frequency band, targeted jamming capability, 24-hour autonomous operation, combined narrowband/frequency hopping defense strategies, black/white list management, and comprehensive model library support covering over 98% of market drones including all DJI models and mainstream brands.
