Detect Drones Without Emitting a Signal
By CRFS
Passive RF sensors can form scalable networks that monitor the spectrum persistently across
wide areas. Unlike library-based systems, they detect any RF emission from drones or their operators—without emitting signals or interfering with other systems. Using COTS hardware and advanced software, the system geolocates threats in real time with high accuracy using 3D TDoA and
line-of-bearing techniques. This TRL-9 technology integrates seamlessly into existing c-UAS architectures via open APIs, enabling multi-sensor fusion and enhanced situational awareness.
