Introduction: Frequent “Illegal Flights” and Safety Challenges
In recent years, with the rapid adoption of drones in logistics, inspection, cultural tourism, and other sectors, urban low-altitude airspace has become increasingly congested. At the same time, incidents such as illegal flights, flight disruptions, and intrusions into energy facilities have occurred with high frequency. The Interim Regulations on the Administration of Unmanned Aircraft Flights, implemented in 2024, require real-name registration and airspace approval. However, enforcement remains difficult in practice. Cities such as Shanghai have already deployed low-altitude sensing base stations based on TDOA (Time Difference of Arrival) technology, exploring solutions that integrate “intelligent detection + real-time management.” Clearly, urban low-altitude UAV security protection has become an urgent necessity.
Pain Points: Why Traditional Solutions Fall Short
| Solution | Function | Drawbacks |
|---|---|---|
| Hardware countermeasures (radar + jammer) | Detection + suppression | High blind spot rate, high cost, interference with civil communications |
| Video + manual monitoring | Recognition | Limited by weather and line-of-sight, slow response |
| Regulatory approval | Management | Difficult enforcement, poor traceability, lack of unified standards |
It is evident that single-dimensional solutions are no longer sufficient to address the dense, dynamic, and complex urban low-altitude environment.
Technical Highlights: Next-Generation Low-Altitude Security Protection System
| Module | Core Function | Technical Specs |
|---|---|---|
| Detection | Multi-modal sensor fusion | Radar + electro-optical + RF, effective against “low, slow, small” drones (<30m/s, <120m altitude) |
| Identification | AI recognition + signal feature analysis | ≥95% recognition rate, ≤2% false positives |
| Positioning | TDOA/AOA multi-base station | Accuracy ≤ ±5m, response ≤ 5s |
| Countermeasures | Multi-level: jamming + forced landing + early warning | Spectrum compliant, adjustable power range |
| Traceability | Cloud management + data logging | Flight paths stored for 30 days, supports legal enforcement |
Key Innovations:
- 5G-A + TDOA fusion sensing, enabling 360° coverage with no blind spots.
- Integrated air-space-ground cloud platform, supporting AI early warning and multi-agency coordination.
- Adjustable jamming power, ensuring minimal interference with legitimate flights and civil communications.
Application Cases: Real-World Data and Validation
| Scenario | Deployment Plan | Results |
|---|---|---|
| Large concert event | Sensing base stations + mobile countermeasure units + cloud platform | Detected 12 illegal drones, forced 6 landings, alerts ≤ 5s, zero safety incidents |
| Power plant protection | Radar + RF + electronic jamming + traceability platform | 18 illegal flights detected in 1 month, 14 interventions, zero operational disruptions |
Data shows that the new system improves detection, recognition, and response speed by more than 50% compared with traditional solutions.
Development Trends and Buyer’s Guid
Key Trends:
- AI + edge computing: Localized recognition to reduce latency.
- Modular design: Rapid deployment for temporary events.
- Multi-source fusion + spectrum compliance: Adapted to complex urban environments.
- Regulation and standardization: Gradual establishment of regional frameworks for the low-altitude economy.
Buyer’s Guide:
| Metric | Recommendation | Rationale |
|---|---|---|
| Detection sensitivity | Able to detect “low, slow, small” drones | Most urban UAVs are small and low-speed |
| Recognition accuracy | ≥95% accuracy, ≤5% false positives | Reduces interference with legitimate flights |
| Response time | Alerts ≤ 5s, countermeasures ≤ 1 min | Prevents escalation of risks |
| Data traceability | Flight paths stored ≥30 days | Meets enforcement and investigation needs |
| Spectrum compliance | Must meet regulatory standards | Minimizes disruption to civil communications |
Conclusion: The Strategic Foundation of Low-Altitude Safety
Urban low-altitude UAV security protection is no longer a battle of “standalone devices.” Instead, it represents a collaborative system of regulations, technologies, and cloud data platforms. Looking forward, intelligent, compliant, and multi-layered protection systems will serve as the strategic foundation for the development of the low-altitude economy, providing robust support for smart city governance and public safety.
