Rezonans-NE Very High Frequency [VHF]

The Rezonans-NE very high frequency [VHF] counter-stealth early warning phased-array radar is designed to effectively detect a wide range of current and future air targets, including low-observable cruise and ballistic missiles, hypersonic aerial vehicles, as well as stealthy ones, in severe electronic countermeasures (ECM) and clutter environment. It is in service with the Russian Air Force, Iran (since 2009) and Algeria (since 2017).

The radar can operate in circular scan mode or within a specified sector. In addition to peacetime tasks, it can provide early warning of an air attack and information support for air and air defence warfare operations. The Rezonans-NE includes up to four radar modules, each of which provides control in the azimuth sector of 90 degrees and can operate independently.

The radar module consists of a transmit antenna-feeder device, receive azimuth and elevation antenna-feeder devices, and a power amplifier. The radar’s data receiving and processing system provides data reception and processing in each of the four modules. Radar equipment is housed in containers. The probing signal generator and radar data receiving and processing equipment are digital and controlled by special processors. A solid power amplifier is used. The radar consisting of the four modules controls the 360-degree sector and occupies a 100 x 100 m area.

• detect and track a wide range of air targets at long ranges, including small and stealthy ones;
• automatically determine the location and motion parameters of air targets as well as classify them;
• automatically provide designations to weapon systems;
• generate and send information about the tracked targets for taking operational decisions;
• analyze the ECM situation and automatically adjust to the actual ECM conditions.

The station was built using only Russian components. Resonance-N has been specially upgraded to work in arctic conditions.

Carlo Kopp noted in 2010 that the VHF band Rezonans N/NE, which is explicitly marketed as “Stealth Air Target Early Warning Radar.” Like the Nebo U/UE series, it takes 24 hours to deploy and is intended for static long-range air defense applications. Production quantities remain unknown at this time. Unlike the Nebo U/UE, it uses electronic beam steering techniques.

The technical capabilities of the Resonance-N radar allow it to detect and issue target designations for aerodynamic air targets at ranges up to 600 km, for ballistic targets - up to 1200 km. At the same time, he discovers targets at altitudes of up to 100 km.

The radar "Resonance-N" is developed on a modular basis. This significantly reduces the cost of its production due to the subsequent assembly of special containers, in which all nodes of the station are located. In the end, this allows you to make the station quite mobile.

Ready containers from manufacturers are delivered by road, rail, water or air to the place of subsequent installation on pre-prepared foundations. If necessary, this radar can be transported very quickly and mounted in a new location. And if necessary, it is also quickly modified to build up combat capabilities by embedding similar containers from the stations of the same type.

Phased antenna array significantly expands the capabilities of the complex, and the locator can automatically exchange data with other radars. The radar station fits on a site measuring 100 by 100 meters. It controls the airspace around in a circular mode, with a 360-degree view. The station is equipped with a friend-or-foe target recognition system and can operate stably both at the lowest and highest air temperatures, with wind speeds up to 50 m / s.

At the same time, the radar is capable of tracking over 500 targets, providing early warning of an air attack and providing information about the air situation to aviation and anti-aircraft defense systems during combat operations.

A feature of the radar complex is the absence of rotating antennas, which are usually used to provide all-round visibility. Here, a circular overview is carried out using electronic means of space control. This significantly reduces the energy supply necessary for the operation of the complex, increases the resource and increases the reliability of the locator. The radar does not lose effectiveness in conditions of electronic counteraction or strong natural interference.

It is important that in the coverage area of the radar complex, all aircraft created using the technology to reduce radar visibility are visible. All this is due to the fact that the Resonance-N radar implements the principle of resonant radar to detect a wide class of air targets. The method has been worked out and tested on various mathematical models both in the field and at the test sites, where it is fully justified.

In the export version, Resonance-NE is supplied to other countries of the world. So, the Egyptian Resonance-NE radar tracks the movement of all objects in the airspace not only over Egypt, but also Israel and Syria. According to a number of sources, in 2020 Russia will begin regular deliveries of Resonance-NE to the Middle East. From the beginning of 2020, supplies of the export version of "Resonance-NE" to Egypt began. Iran and Syria are next.
