Protection of educational institutions, children's recreation centres and medical facilities from UAVs

We offer a security system preventing drones from trespassing borders of your facility and causing any damage to it. The system consists of a transmitters set, which is united by a common monitoring and control system, and jams control and navigation channels on different frequencies.

The "Barrier RI Kupol" UAV protection complex is basically a multi-frequency system of radio-electronic suppression of radio control channels and satellite navigation, which provides effective influence on UAV receiving devices in a constant mode or based on signals from external detectors.

The effect of electronic suppression and blocking of the controlled flight of a UAV is achieved by creating in each frequency range at the input of these receiving devices a power density of the interference signal that exceeds the level of the control or navigation signal. However, that's not all. Due to the extremely complex structure of such signals, the use of pseudo-random frequency hopping mode (PRFC - more than 1000 jumps per second) and other on-board interference rejection systems in their formation, interference signals are generated according to certain algorithms in software using special devices.

Our systems have a multi-position structure, which allows:

1. influence the UAV from different angles and level its capabilities for spatial detuning from interference,
2. take into account complex terrain, object configuration, exclude “dead zones” (areas in which radio interference signals do not propagate);
3. take into account the radio frequency layout of the facility (maximize the impact on radio equipment at the facility itself or nearby facilities);
4. ensure sanitary standards for radiation levels of microwave signals.

An important advantage of the system is its open architecture and the ability to integrate with any security system already installed at the facility.

The local protection system (LPS) of an object is a set of protection complexes (SC) “BARRIER RI Kupol” united by a common task to be solved and a monitoring and control system .

Depending on the configuration of the object, its location, terrain, the presence of high-altitude objects around, the need to ensure electromagnetic compatibility with radio devices located at the object, the degree and nature of threats (threat models), the number and composition of short circuits for different LPS may be different. Each such complex may include a different set of object protection devices (RPDs), which are radio jammers for drone radio communication channels (onboard receivers of control signals, including control signals for FPV drones and satellite navigation signals). RCDs (interference transmitters) differ in the operating frequency range at which interference signals are emitted, the structure (type) and level (power) of such signals (which in turn correspond to the structure, frequency ranges and level (power) of the Drone control and navigation signals) . In addition, to create interference signals of different frequency ranges that are sufficiently effective in structure and level, different numbers of RCDs are required.

In one case there may be 1–2, in another – 4 or more. The need to increase the number of transmitters of interference signals in the same frequency range is caused not only by the need to increase the output power of such a signal, but also mainly by the complex structure of drone control signals and the increasingly improved anti-jamming system of drones.

The composition of the RC “Barrier RI Kupol” may include:

1. up to 4 BARRIER 1.0 devices. Suppression of UAV control channels in the frequency range 2390–2500 MHz;
2. up to 4 BARRIER 1.1 devices. Suppression of control channels (including FPV - Drones) in the frequency range 5715–5860 MHz;
3. up to 4 BARRIER 1.4 devices. Suppression of control channels in the frequency range 5150–5250 MHz);
4. at least one BARRIER 1.2 device. Suppression of control channels (including FPV - Drones) in the frequency range 420–460 MHz);
5. at least one device “BARRIER 1.3. Suppression of control channels (including FPV - Drones) in the frequency range 855–930 MHz;
6. at least one BARRIER 1.5 device. Suppression of control channels (including FPV - Drones) in the frequency range 1180–1220 MHz;
7. at least two BARRIER N devices. Suppression of satellite navigation channels.

In addition, the “Barrier RI Kupol” short circuit can include radio frequency detectors of video signals and telemetry signals of basic frequencies (2400 and 5800 MHz), emitted by the drone’s transmitting devices - RFD (radio frequency detectors). Depending on the area of ​​the object, the conditions of its location, the radio frequency background around the object (the presence of noise, interference at these and other frequencies in the area of ​​the object), the threat model, a different number of RFD of different frequency ranges can be included in the short circuit.

The first ones are intended for installation on the cover of stationary objects (enterprises of various industries, objects of the oil and gas and chemical industries, transport and energy industries) and, as a rule, are mounted on a permanent basis on already constructed structures (buildings, structures, stationary fences, lighting points or towers radio or television communications). They are designated “Barrier RI Kupol-S” and are connected to the electrical networks already deployed at the sites. To control and manage such complexes, wired communication channels existing at the facility are mainly used. KZ "Barrier RI Kupol-S" can be integrated into the technical security system already created at the facility (ACS, video surveillance system, pyramidal security or fire safety).

Mobile complexes are intended mainly to cover temporary objects with variable deployment or objects located in facilities unequipped in terms of engineering, as well as vehicles in parking lots (stops) or in motion (various vehicles, sea and river vessels, drilling platforms, trains ). They have the designation KZ “Barrier RI Kupol-M”. They can be placed on both stationary and movable structures (tripods, pipe stands), as well as mounted on trees or other natural objects.

The LPS, built from the Barrier RI Kupol, of various compositions, provides round-the-clock, year-round protection of objects (provides for a mode of constant radiation of radio interference) in any meteorological and climatic conditions.

In addition, a controlled operating mode of the LPS is provided, which allows you to turn on and off the short circuit "Barrier RI Kupol" in automatic (based on signals from detection equipment) or in automated (based on operator/duty commands) modes, depending on the air situation or for other reasons.

When developing and creating the Barrier RI Kupol defense complex, many years of experience of the company’s scientists and designers, deep knowledge of the theory of radio physics, radar and electronic warfare, domestic and foreign experience in creating an air defense system for critical facilities were used.

The basic principle underlying the Barrier RI Kupol short circuit is its spatially distributed structure (multi-position), which makes it possible to detect UAVs and carry out radio-electronic interference on them simultaneously from several directions, with different emitted frequencies and structure of radio interference signals. In turn, this allows:

1. limit the power of emitted interference signals at the level of sanitary standards;
2. significantly reduce the effectiveness of the drone’s noise protection system (due to the need for special software to simultaneously take into account several directions of the drone’s exposure to interference).

Additional benefits include:

• Operational configuration of the complex for emerging tasks and the geometry of the protected object (creation of “barriers” in threatened directions; creation of a “dome” of protection over the object; formation in one or more echelons);
  
• Electromagnetic compatibility, environmental friendliness, high secrecy (the Complex does not create radio-electronic interference to other electronic zones);
• Information compatibility with any other means of detection, communication, control and display;
• Compatibility with other means of neutralizing UAVs;
• Profitability of use;
• Compliance with the required levels of microwave radiation, sanitary and hygienic standards and rules; possibility of use in populated areas;
• Creation of large-scale object protection fields to detect objects capable of moving in the air and cross-border environments;
• It is possible to use third-party (foreign) illumination sources, which significantly reduces the cost of the RRS and makes it completely “invisible”;
• Elimination of gaps in the visibility zones of combined radars in hard-to-reach and rugged (mountainous) terrain;
• Ensuring resistance to interference;
• Simple modular design;
• Independence from external sources of illumination signal;
• Combination of a backlight transmitter and a jammer in one device;
• Low cost;
• Small weight and size indicators;
• Low power consumption;
• Autonomy.

Our company’s equipment’s design and manufacture are based on the basic principle of air defense "Constant Readiness" and "High Security". These principles, among other things, stipulate efficiency and minimal human involvement in operation of complexes, almost self-contained operation of equipment’s and high MTBF.

It allows to control the equipment’s operation and necessary service works on its maintenance even by specialists without any profiled qualification.

We conduct training of complex’s operating during its installation or remotely. This training does not take much time.
