Drone Guard is a compact light weight scalable drone detection and disruption System. The detection layer is based on compact radar, capable of detecting and tracking the drones. The radar triggers the other layers of the protection suite. As a result of the radar detection an Electro-Optical (EO) system that is cued to the suspected drones for classification and identification. The second layer provides the countermeasures used to disrupt the target flight. These are activated from the command and control centre based on inputs from the radar and EO sensors. Countermeasures include cueing a jammer to the target or a weapon mount to physically destroy the target.
