The fixed deployment plan of Kongyu Technology belongs to a long-term deployment plan, which is suitable for situations where the airport prevention and control scope remains basically unchanged for a long time. In airport planning, the clearance protection range is usually determined, so except for airports built in stages, most cases are suitable for fixed deployment plans. The deployment plan usually adopts a central deployment method, installing the defense system in the central position of the protected area to achieve a larger expected protection range. The system mainly adopts a strategy of combining multi station positioning radio equipment and optoelectronic tracking and identification equipment. When a drone is discovered, the drone pilot is located, and the airport public security uses a strategy of combining directional interference disposal equipment with portable jamming guns. Under the control of the command and control software, electronic interference is directed to the drone target, blocking the signal transmission link, causing the interfered drone to return or make an emergency landing, capturing the pilot, and confiscating the flight equipment.
