📡 What Are RF-Based Detection Systems?

Radio Frequency (RF)-based drone detection systems are passive sensors that monitor the electromagnetic spectrum to detect, classify, and track drones by identifying their radio signals. These systems can operate without emitting signals themselves, making them ideal for stealthy or sensitive deployments.

🔍 How They Work

• Signal Detection: Identify radio transmissions from the drone or its controller (2.4 GHz, 5.8 GHz, etc.)
• Fingerprinting: Match unique signal patterns (MAC address, packet timing, modulation)
• Direction Finding (DF): Triangulate signal origin to localize the drone and pilot
• Geofencing Alerts: Trigger alarms when unauthorized drones enter restricted airspace

🛠 Key Features

• Passive, non-emitting operation
• Real-time detection and tracking of multiple drones
• Wideband scanning with SDR (Software-Defined Radio)
• Integration with radar, EO/IR, and acoustic sensors for layered defense

🎯 Deployment Use Cases

• Airports and seaports
• Government buildings and embassies
• Battlefield perimeter monitoring
• Mobile tactical operations (vehicle-mounted)

⚠️ Limitations & Considerations

• Less effective against pre-programmed autonomous drones without RF emissions
• Performance depends on RF environment and noise levels
• Susceptible to spoofing or encrypted signals
