Frequently Asked Questions

Q: What is the main advantage of passive detection over active radar?

Passive detection does not emit any radio frequency signals, making the system completely undetectable by the drone or the operator, providing a critical strategic advantage in covert security.

Q: Can this system detect customized or military-grade drones?

Yes, our broadband spectrum detector is designed to identify a wide range of signals, including those from customized frequencies and specialized wireless communication devices.

Q: How does the AOA technology determine the drone's location?

Angle of Arrival (AOA) measures the phase difference of the signal arriving at multiple antenna elements, calculating the precise vector of the signal source to locate the drone.

Q: Is the 10km range guaranteed in urban environments?

The 10km range is optimal in clear line-of-sight conditions. In urban areas, signal attenuation from buildings may reduce range, but the AOA precision remains highly effective.

Q: Does the system integrate with drone jamming hardware?

Absolutely. The system is designed to work seamlessly with fixed chassis jammers, vehicle-mounted jammers, and handheld devices to create a full detect-and-neutralize loop.

Q: What maintenance is required for the passive detector?

Because it is a passive system with no high-power transmitters, maintenance is minimal, primarily focusing on software updates and periodic antenna inspections.
