FAQ | Passive Drone Acoustic Localization System | Technical Support

Frequently Asked Questions

All Your Questions About Passive Acoustic UAV Detection & Localization Systems Answered

This FAQ covers core technical specifications, operating principles, deployment scenarios, accuracy, integration, and performance of our passive drone acoustic detection solutions designed for defense, security, and industrial users.
1. How does passive drone acoustic localization function?
It uses high-sensitivity MEMS microphone arrays to capture unique acoustic signatures emitted by drones. AI-powered signal processing then calculates real-time position, direction, and distance in complete passive mode with no signal transmission.
2. What advantages does acoustic detection have over radar and camera systems?
Acoustic systems run 24/7 in all weather conditions, bypass radar blind zones, penetrate visual obstacles, and remain fully functional in complete darkness, fog, rain, or strong glare that disables optical systems.
3. What detection range does the system provide in urban environments?
In dense urban areas, the detection range is 0–150 meters. In quiet open areas, it reaches up to 500 meters. Multi-array networking further extends coverage to 2–5 km for large-scale security projects.
4. How precise is the positioning for low-altitude drones?
Azimuth accuracy reaches 5 degrees for hovering drones. When three or more arrays work together, positioning error is limited to 10 meters or 10% of the detection distance, whichever is greater.
5. Does the system support full 360° monitoring coverage?
Yes, it provides full 360° azimuth monitoring and supports elevation angles from -20° to 90°, eliminating blind spots for low-altitude security and surveillance.
6. How many drones can be tracked at the same time?
The system can track up to 3 drones simultaneously under standard configuration. Custom upgrades are available for projects requiring higher target tracking capacity.
7. What is the real-time response speed of the system?
The positioning response time is only 100ms, enabling instant early warning and rapid tracking for sudden, unauthorized drone intrusions.

It operates 100% passively with no signal transmission, making it extremely suitable for military zones, sensitive facilities, and covert security deployments.
9. How does the system handle urban noise and interference?
Built-in AI noise reduction and anti-interference algorithms filter out ambient clutter, ensuring stable detection performance in busy cities, industrial zones, and complex environments.
10. What are the key AI recognition performance metrics?
The drone recognition rate exceeds 90%, while the false alarm rate remains below 10%, supporting reliable 24/7 unattended operation.
11. What is the effective detection altitude for drones?
Field tests confirm stable detection and positioning at altitudes between 114m and 140m, making it ideal for low-altitude airspace management.
