Hovering Crowd Control Beam
Helicopters now serve as the platform for a device that uses a microwave beam to cause a painful sensation in the skin of targeted individuals.
The transmitting antenna on the current system is 2 metres across, produces a single beam of similar width and is steered mechanically, making it cumbersome. At the heart of the new weapon will be a compact airborne antenna, which will be steered electronically and be capable of generating multiple beams, each of which can be aimed while on the move.
