The AOA Passive Spectrum Drone Detector is a professional-grade surveillance system engineered for wide-area airspace security. Utilizing advanced Angle of Arrival (AOA) technology, this system provides high-precision detection and localization of unmanned aerial vehicles (UAVs) without emitting any radio signals, making it completely undetectable to the target drone.

Designed for critical infrastructure protection and border security, this system can monitor spectrum activity up to a 10km radius. By analyzing the phase difference of incoming signals across multiple antennas, it delivers real-time spatial coordinates of unauthorized drones, ensuring comprehensive situational awareness for security personnel.

Frequently Asked Questions

Q: What is the difference between Active Radar and Passive AOA Detection?

Active Radar emits radio waves to detect objects, making it detectable to enemy sensors. Passive AOA detectors only "listen" to the radio signals emitted by the drone and its controller, making the detector completely invisible.

Q: Can this system detect drones that are flying in autonomous mode (no RF link)?

Passive RF detectors rely on signal transmission. For fully autonomous drones with no RF emission, we recommend integrating our Photoelectric Detectors or Radar components for a multi-layered defense.

Q: How does the 10km detection range work?

The system uses high-gain antenna arrays and sensitive spectrum analyzers to pick up low-power control signals and telemetry data from drones up to 10km away, depending on terrain and interference.

Q: Is the system compatible with existing Jammer Systems?

Yes, it is designed to work as the "eyes" of a C-UAS system. Once the AOA detector localizes the target, it can trigger a vehicle-mounted or fixed chassis jammer to neutralize the threat.

Q: Does this device require a specialized license to operate?

Since it is a passive receiver and does not transmit any radio frequency, it generally has fewer regulatory restrictions than active jammers or radars, but we recommend checking local laws.

Q: How accurate is the Angle of Arrival (AOA) localization?

The system provides high angular precision. By utilizing multiple antenna elements, it can narrow down the drone's position to a specific bearing, allowing security teams to pinpoint the target's location effectively.
