Introduction: Frequent Illegal Flights and the Rise of Electronic Countermeasure Needs
With the widespread use of drones in logistics, inspection, and security, urban low-altitude airspace has become increasingly congested. However, illegal flights, disruptions to civil aviation, and intrusions into sensitive facilities occur frequently. In 2024, domestic airports recorded more than 300 incidents of drone interference with flights, with some delays exceeding 40 minutes. Facing rapidly escalating low-altitude security challenges, UAV electronic countermeasure technology is becoming an essential weapon for urban safety management.
This technology not only enables the detection, identification, and intervention of illegal drones but also provides end-to-end low-altitude safety management under regulatory compliance. This article analyzes the current state and future prospects of this key technology from the perspectives of pain points, technologies, application cases, and trends.
Pain Points: Limitations of Traditional Low-Altitude Protection Methods
| Traditional Approach | Drawbacks |
|---|---|
| Manual patrol + electro-optical monitoring | Limited by weather, lighting, and manpower; slow response and high false alarm rates |
| Conventional radar + jammer combination | Unable to distinguish between legal and illegal drones, risk of mis-interference |
| Regulatory approval | Separation of supervision and enforcement, poor information flow, delayed illegal drone detection |
Traditional measures are often reactive or single-point defenses, lacking the capability to achieve all-time, full-chain, intelligent protection. As a result, urban low-altitude security faces enormous challenges.
Technical Highlights: Core Modules of UAV Electronic Countermeasure Technology
UAV electronic countermeasure technology primarily covers five stages: detection – identification – interference – control – traceability. Core modules include:
- RF detection and positioning: Utilizing algorithms such as TDOA/AOA for passive detection and real-time positioning, with accuracy up to ±5m.
- AI-based intelligent recognition: Combining image recognition with signal feature analysis to distinguish civil, commercial, military, and illegal drones, with ≥95% accuracy.
- Directional electronic jamming: Controllable jamming range and power, supporting 2.4GHz, 5.8GHz, GPS, and other bands, minimizing interference with legitimate flights.
- Link takeover and forced landing control: Some systems can seize drone control links to ensure safe return or forced landing, enhancing public safety.
- Data tracking and compliance management: All flight paths and intervention records are stored in the cloud, supporting law enforcement and accountability.
Innovations:
- Multi-sensor fusion (radar + electro-optical + RF + acoustic) for all-weather, all-direction detection.
- AI + edge computing for millisecond-level response, reducing cloud latency.
- Modular design for rapid deployment in temporary events or key areas.
Application Cases: Real-World Validation of Technology Value
Case 1: Low-Altitude Security for Large-Scale Events
At an international marathon in 2025, a UAV electronic countermeasure system was deployed. The system detected 23 drones throughout the event, 8 of which were illegal. It completed identification and alerting within 3 seconds, forced 6 drones to land, and ensured zero safety incidents.
Case 2: Energy Facility Protection
In 2024, a coastal nuclear power plant installed directional jamming and link takeover systems. Within 3 months, 12 illegal drones were intercepted, reducing illegal flight rates by 72% with zero disruption to operations.
These cases demonstrate that electronic countermeasure technology ensures low-altitude security in complex environments, transforming defense from passive protection to proactive control.
