As drone threats escalate globally, counter-drone (C-UAS) systems have diversified into multiple technological approaches. This article objectively examines the current landscape of defense methods and representative commercial products available worldwide.
1. Detection & Tracking Technologies
Radar Systems
- Capabilities: Detect micro-drones (0.01m² RCS) with 0.2m precision, track 200+ targets simultaneously.
- Example: AUDS (UK) – Integrates radar, EO/IR, and RF for 360° coverage.
Electro-Optical/Infrared (EO/IR)
- Capabilities: AI-powered classification (>99% accuracy), tracks 0.5cm targets in adverse weather.
- Example: Hensoldt Spotter (Germany) – Multi-spectral tracking for urban environments.
RF Spectrum Monitoring
- Capabilities: Detects 2.4GHz/5.8GHz control signals, identifies drone models via signature analysis.
- Example: DroneDetect (US) – Portable RF scanner for law enforcement.
2. Soft-Kill Countermeasures (Non-Destructive)
GNSS & RF Jamming
- Capabilities: Disrupts drone control & navigation, forcing return/landing.
- Example: Skylock (Israel) – Civilian-compliant, low collateral risk.
Spoofing & Cyber Takeover
- Capabilities: Mimics control signals to hijack drones mid-flight.
- Example: Dedrone RF Capture (US/Germany) – Protocol-specific takeover.
3. Physical Interception (Non-Lethal)
Net Capture Systems
- Capabilities: Deploy nets via ground launchers or interceptor drones.
- Example: SkyWall (UK) – Net-firing launcher (200m range).
Interceptor Drones
- Capabilities: High-speed UAVs collide with or net hostile drones.
- Example: GOBI (France) – 250km/h intercept drone (5km range).
4. Hard-Kill Neutralization
Laser Systems
- Capabilities: 10kW lasers disable drones at 1km (0.3s engagement).
- Example: Raytheon HELWS (US) – Vehicle-mounted anti-drone laser.
High-Power Microwave (HPM)
- Capabilities: Area-denial against drone swarms.
- Example: Epirus Leonidas (US) – Drone swarm suppression.
5. Emerging & Hybrid Solutions
- AI-Powered Decision Systems: Auto-selects optimal countermeasure (e.g., jamming vs. laser).
- Drone Swarm Defense: Distributed sensors + coordinated interceptors.
