LTE Radar listens to the mobile network
A passive-radar system that uses existing LTE transmissions to detect and track airborne and ground objects without transmitting its own signal.
Field notes
The page describes a three-stage passive-radar workflow: cellular transmissions illuminate the area, a receiver captures direct and reflected signals, and processing separates moving signatures from stationary background. Its examples distinguish hovering from flying multi-rotor craft through rotor modulation, while road and heavy vehicles are classified through motion and plot stability. The illumination map is explicitly modelled from population distribution and typical network structure, not presented as an operator’s actual site registry.
