ZJ-TY1881 Detection & Jamming UAV/Drone Defense System connects different low altitude detection radars, detectors, Jammers, and coordinates them together to provide a defense airspace by detecting and jamming various UAVs. This system realizes real time detection and real time jamming. Response time is less than 0.1 s after detecting objects. This system not only provides early warning for UAV, but also supports the closed-loop detection of its control system. It can detect not only UAVs, but also illegal radio sources which can jam UAVs.
