59N6 Protivnik-GE / "Enemy-GE"

By around 2010, the army began to enter the development of the same Nizhny Novgorod NNIIRT mobile three-coordinate radar 59N6 "Enemy-GE". This radar is designed to detect, determine the coordinates and escort strategic and tactical aircraft, ASALM missiles, small, low-speed aircraft, recognize target classes, determine the state of aerial objects, direction finding directors of active noise interference, provide radar information for guiding fighter aircraft and target designation of anti-aircraft missile systems when operating as part of an automated and non-automated subsection air defense, display of individual and flight information at the workplaces of the operators of the radar station and remote devices received in the systems "Sentinel" ("Password") to ensure the safety of flights of their aircraft,

This works in the UHF band, therefore, having about the same ability to detect stealth targets, to more accurately determine their coordinates. This accuracy is sufficient not only to issue an "informational" data to the command post, but for target designation for air defense fighters and SAM missiles.

Volume of equipment is greater than the "Niobium-SV". The station will be located on two wheel chassis.

The multimode 3D-radar Protivnik-GE (russian designator: 59N6-E cyrillic: 59H6-E) designed to provide long-range accurate aircraft position data (range, bearing and height) for air defence, tactical control and navigational assistance for both close air support and counter air operations. This radar has been developed by Nizhny Novgorod Science Research Institute Of Radio Engineering (NNIIRT) in Russia. The whole system is mounted on two semi-trailers and has an operating range of about 600 km. The fifth-generation universal, mobile, three - coordinate radar station Opponent-GE (59N6-E) is designed to detect and provide coordinates (range, azimuth, altitude) of air targets when operating as part of air defense control systems and air traffic control (ATC) systems. The station was developed at the Nizhny Novgorod Research Institute of Radio Engineering (NNIIRT). All the equipment "Opponent-GE" fits in two vehicles. The high mobility of the locator was confirmed by a march of 600 km, which was carried out from Nizhny Novgorod to Zhukovsky on MAKS-97.

The radar is capable of providing intense information without the need for further clarification to simultaneously provide information for guiding fighters and targeting anti-aircraft missile divisions. Altitude viewing airspace - up to 200 km, i.e. The station is capable of detecting low-orbit satellites in near space. The phased antenna array of the station formulates the radiation pattern in the sector 0-45 , and due to the supernova level of the side lobes, it automatically provides high protection of the locator from actively noise interference.

It was possible to achieve the advantages of high accuracy of coordinate measurement by creating a unique headlamp with digital spatio-temporal signal processing. Opponent-GE, in addition to three coordinates, determines the fourth parameter - the radial speed. This allows cuttig off false targets. In total, the locator accompanies up to 150 air objects. The radar provides everything to successfully detect the fifth-generation aircraft being created.

The radar antenna largely determines the effectiveness of the radar and allows putting it in one transport unit. The size of the antenna is 5.5x8.5 m, rotation speed is 6 or 12 revolutions per minute. This corresponds to the data output time after 10 and 5 seconds, respectively, which is enough to work on high-speed and highly maneuverable targets. Aircraft made using stealth technology with EPR less than 0.1 sq. m., the station discovers at a range of up to 200 km.

The antenna of the station forms 20 identical beams in 10 blocks. The radar provides automatic adaptation to the state of the station: if one unit fails, the coefficients change - the rays expand slightly and 45 of airspace is viewed not by 20, but by 18 rays. The entire field of view is preserved, but the accuracy of measuring the coordinates of the target is slightly reduced, and the side lobes increase within the acceptable range. The unified construction of the radar in two ranges reduces the cost of spare parts and fuel and lubricants.

The principles of building the locator allows upgrading the base radar in other wavelengths, improve performance. Opponent-GE was conceived as a massive high-potential station. It uses the international frequency range of 23 cm. A secondary locator is built into the radar, which can provide air traffic control with great information acquisition capabilities. This is not only a friend-or-foe identification system for air defense, the secondary locator will also report on the fuel supply, receive a distress signal and other messages.

The radar has a high degree of measurement process automatization and a high-resolution under intensive countermeasures. There are air route data processing, secondary air traffic control radar and suitable interface to any automatic control systems. Automatic diagnostics, monitoring and fault finding system are the features of this radar. The automatic mode of operation is also possible. Air search coverage of the radar extends to 200 km in height, i.e. this radar can discover satellites into the near orbit. All necessary information is read out in digital shape from a tricolor plan position high-aspect ratio display. Radar maping is possible.

The phased-array antenna forms 20 Pencil beams covering an elevation of total 45 degrees. The radar uses pulse compression to increase range accuracy and resolution and give a effective protection against noise jamming. The radar uses an adaptive beam scheduling processing by 10 redundant receiverchannels The application of standardised sub-assemblies provide an easy maintenance with help of a stock of spare parts.

High accuracy of determining the target coordinates provided by UHF, digital phased array antenna and processing extracted from the antenna signals on a high-performance processor using efficient algorithms. "Enemy-GE" capable of detecting targets with RCS less than 0.1 sq. m. (as in cruise missiles and, in fact, have the same stealth aircraft) at a distance of 200 km, with ESR of 1.5 sq. m. (fighter with reduced visibility) at the distance of 340 km.

The station has a high degree of protection from interference influence of the enemy. The target detection range in altitude: 100 m 40 km 1000 m 100 km, 5000 m 240 km, 12 km 340 km. At the same time tracked back to 150 targets. Deployment time station is 40 min.

Protivnik-GE is in production since 1990. It raise the effectiveness of the air defense network of the air force and the air raid defences of the army. In 1999, it was supposed to release the first production station. It will be able to be effectively used in the Air Force, Air Defense and missile defense in the Ground Forces, the Rapid Reaction Forces and in the Federal Aviation Service.

The Ministry of Defense of Belarus signed a number of contracts at the Army-2019 international military-technical forum, the ministry said. So, a contract was signed in June 2019 for the supply of additional components for the Opponent-G radar stations, which are on alert to guard the state border of Belarus in the airspace.

The three-axis radar was seen in the desert area of El Ghiza - in the area of the settlement "Names on October 6". It is known that the Opponent-GE radar of the decimeter wave range has a digital antenna array. In Egypt, from October 26 to November 7, the first joint Russian-Egyptian air defense exercises Strela Druzhby-2019 was held. The Russian army was represented by anti-aircraft gunners of the Southern Military District. A total of 300 troops. The Buk and Tor missile systems, as well as Igla MANPADS and Shilka anti-aircraft self-propelled guns, were involved in the technology.
