The AOA Passive Spectrum Drone Detector is a professional-grade security solution designed for long-range aerial surveillance and threat mitigation. By utilizing advanced Angle of Arrival (AOA) technology, this system can precisely locate unauthorized drones within a 10km radius without emitting any detectable radio signals, ensuring complete stealth during operation.

Engineered for high-sensitivity spectrum analysis, the detector identifies drone communication protocols and control frequencies in real-time. It provides security operators with critical situational awareness, allowing for the early detection of intruding UAVs to protect sensitive infrastructure, government facilities, and restricted airspaces.

Frequently Asked Questions

Q: What is the primary difference between AOA detection and traditional radar?

Unlike radar, which emits pulses to find objects, AOA (Angle of Arrival) is passive. It listens for the radio signals emitted by the drone and its controller, making the detector undetectable to the intruder.

Q: Can this system detect drones that are flying in autonomous mode without RF signals?

Passive spectrum detectors rely on RF emissions. For fully autonomous drones without RF links, we recommend integrating this system with our Photoelectric Detectors for a hybrid solution.

Q: Does the 10km range apply to all types of drones?

The 10km range is optimized for standard high-power control links. Detection distance may vary based on the drone's transmission power, environmental interference, and antenna height.

Q: How does the system handle signal interference in urban areas?

Our system utilizes advanced digital filtering and spectrum analysis to distinguish between common Wi-Fi/LTE noise and specific drone control protocols, minimizing false positives.

Q: Can the AOA detector be integrated with a Jammer System?

Yes, it is designed to work as the "eyes" of a C-UAS system. Once the AOA detector identifies the location, it can trigger a Jammer System to neutralize the threat automatically.

Q: What is the maintenance requirement for the AOA Passive Spectrum Detector?

Maintenance is minimal as the system contains no moving parts. Periodic software updates and physical inspections of the antenna array are recommended to ensure peak performance.
