Architecture of the TDK Barrier RI Kupol
The company "Rubezh-Engineering," based on its own expertise and manufactured equipment, scientific developments, and many years of cooperation with leading security solution providers, creates solutions to protect critical infrastructures from UAV threats.
The Tactical Defense Kit "Barrier RI Kupol" ensures the tasks of detection, classification, and suppression of drones.
Threat Model Development
Learn more about threat model development for UAV object protectionThe number and composition of the defenkit for different local protection systems may vary depending on the characteristics of the object, the surrounding areas, and the developed threat model.
Additionally, the characteristics of the kit will differ based on the frequency range of the jamming signals, the structure, and the power levels of these signals.
According to the emission sector, the protection systems are divided into:
- Omnidirectional, creating a protective dome;
- Sectoral.
Depending on the configuration and size of the objects, the adopted threat model, the expected types of UAVs, and the characteristics of their communication systems, protection of objects can employ either only "dome" or "sectoral" types, or a combination of both.
The advantages of the protection kit include a multi-frequency electronic jamming system for radio control channels and satellite navigation, which ensures effective impact on UAV receiving devices either continuously or based on signals from external detectors.
The effect of electronic jamming and blocking of UAV controlled flight is achieved by creating a signal jamming power density at the input of these receiving devices in each frequency range, exceeding the level of the control or navigation signal, which is generated by specialized devices using specific algorithms.
Thus, our devices are not primitive "jammers" but represent a hardware and software complex.
Our systems have a multi-position structure, which allows:
- Impacting UAVs from different angles and neutralizing their ability to spatially tune out interference;
- Considering the complex terrain, object configuration, and eliminating "dead zones";
- Taking into account the radio frequency plan of the object, minimizing impact on radio equipment at the object itself or nearby objects;
- Ensuring compliance with sanitary norms for microwave signal emission levels.
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 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:
- up to 4 BARRIER 1.0 devices. Suppression of UAV control channels in the frequency range 2390–2500 MHz;
- up to 4 BARRIER 1.1 devices. Suppression of control channels (including FPV - Drones) in the frequency range 5715–5860 MHz;
- up to 4 BARRIER 1.4 devices. Suppression of control channels in the frequency range 5150–5250 MHz);
- at least one BARRIER 1.2 device. Suppression of control channels (including FPV - Drones) in the frequency range 420–460 MHz);
- at least one device “BARRIER 1.3. Suppression of control channels (including FPV - Drones) in the frequency range 855–930 MHz;
- at least one BARRIER 1.5 device. Suppression of control channels (including FPV - Drones) in the frequency range 1180–1220 MHz;
- 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 Rubezh-Engineering company specializes in the production of two main modifications of anti-drone systems – stationary and mobile.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.
There are three possible scenarios when suppressing a UAV:
- If the control signal is lost, the UAV, depending on the algorithm of its software, will either return to the landing point or make an emergency landing.
- If the satellite navigation signal is lost, the UAV will switch to flight using the on-board inertial navigation system (if available), while returning to the starting point will be practically impossible, and an emergency landing may be hard. Control of a UAV in the event of a loss of navigation signal can only be carried out by a trained operator who has encountered similar situations.
- If control and navigation signals are lost at the same time, the probability of a UAV crash is high.
For UAVs flying along a route specified by the flight program (in radio silence mode), as a rule, in any case, constant or periodic adjustment of this route is required using a global navigation satellite system. Therefore, suppression of navigation channels for such UAVs also remains critical.
Before you equip your facility with any protection system based on electronic interference against the UAVs threat, , you should know that the remote radio control of these UAVs is carried out, as a rule, on frequencies coinciding with the frequency ranges of various networks of wide and specialized communications (trunking - 433 MHz, GSM - 900, 1800 and 2100 MHz, WI-FI - 2400, 5200, 5800 MHz). Reception of signals of global navigation satellite system of UAV is also carried out by standard radio channels GPS, GLONASS, etc.
Therefore, when switching on the "Barrier RI Kupol" protection complex in the radius of action of jamming devices, there may be a short-term or permanent, partial or significant decrease in the quality of communication in these frequency ranges. The principles of operation and manufacturing technologies of our products allow us to form directional fields of electronic interference, "bypassing" the antennas of your receiving devices and keep communication stable. We carefully choose the places of installation of jammers and try to ensure their minimal impact on the means of communication, especially those providing technological processes of your object.
However, the laws of radiophysics are inexorable. The frequencies of UAV control channels are set by their manufacturers, and there is no other way but to suppress control signals on these frequencies.
You must decide for yourself what your priorities are: comfortable radio communication in all frequency ranges or safety!
Our specialists will help you to study the radio frequency plan of your object and choose the optimal equipment composition, its installation locations and modes of operation.
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:
- limit the power of emitted interference signals at the level of sanitary standards;
- 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.
