Counter-Drone RF System

The Counter-Drone RF system detects drone presence by analysing signaling channel and radio transmission. The system detects the control signal of the drone and alerts security forces of its presence.

The system activates the jamming system once it detects an unapproved drone. An excellent set of RF electronic Countermeasures surrounds the drone's protected perimeter 360° or 90° to disassociate it from its controlling signals and to make it either halt at the current location or move away from it.

This deployment method can be used when obstacles may block the radar's line of sight.
