FIELD: anti-aircraft defence.
SUBSTANCE: invention relates to means of combating unmanned aerial vehicles (UAVs) for various functional purposes and can be used in systems for protecting objects, territories, and airspace zones that involve detecting an UAV and countering it with radio suppression and fire weapons. The technical result of the invention is to increase the effectiveness of protecting objects from unauthorized use of UAVs. The composition of the declared system for detecting and countering unmanned aerial vehicles includes a complex for detecting and tracking UAVs, implementing a difference-rangefinder method for detecting an aircraft, consisting of a central and three peripheral receiving posts, united by an intra-complex communication system, a complex of countering UAVs with means of radio interference, including a post for suppressing radio communication channels, a post for suppressing receivers of the global navigation satellite systems (GNSS), and emitting false navigation signals, a control complex with communication lines.
EFFECT: passive detection, determination of the current coordinates, course and speed of the unmanned aircraft based on the signals from their radio modems, generation of radio interference to receiving devices of radio communication and radio navigation channels, as well as generation of false GNSS signals.
