Nebo SVU
The Nebo-SVU (also known as 1L119) (in Cyrillic: Небо-СВУ, 1Л119) is an very high frequency multi-functional radar and first radar with an active electronically scanned array antenna operating in the metric wavelength. The radar was introduced in 2001 as a replacement for Nebo-SV. Nebo-SVU radars can detect F-22, B-2, F-35 warplanes. It can locate aircraft or other flying object with radar cross-section at . History VHF radar systems have wavelengths comparable to aircraft feature sizes and should exhibit scattering in the resonance region rather than the optical region, allowing most stealth aircraft to be detected. Soviet Union was known for developing VHF radars with counter-stealth capability as P-12 and P-18 radars. Request to detect stealthy aircraft's and provide anti aircraft systems with their coordinates prompted Nizhny Novgorod Research Institute of Radio Engineering (NNIIRT) to develop VHF AESA Nebo-SVU with digital signal processors, which is capable of pe ...

Very High Frequency
Very high frequency (VHF) is the ITU designation for the range of radio frequency electromagnetic waves ( radio waves) from 30 to 300 megahertz (MHz), with corresponding wavelengths of ten meters to one meter. Frequencies immediately below VHF are denoted high frequency (HF), and the next higher frequencies are known as ultra high frequency (UHF). VHF radio waves propagate mainly by line-of-sight, so they are blocked by hills and mountains, although due to refraction they can travel somewhat beyond the visual horizon out to about 160 km (100 miles). Common uses for radio waves in the VHF band are Digital Audio Broadcasting (DAB) and FM radio broadcasting, television broadcasting, two-way land mobile radio systems (emergency, business, private use and military), long range data communication up to several tens of kilometers with radio modems, amateur radio, and marine communications. Air traffic control communications and air navigation systems (e.g. VOR and ILS) wo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Active Electronically Scanned Array
An active electronically scanned array (AESA) is a type of phased array antenna, which is a computer-controlled array antenna in which the beam of radio waves can be electronically steered to point in different directions without moving the antenna. In the AESA, each antenna element is connected to a small solid-state transmit/receive module (TRM) under the control of a computer, which performs the functions of a transmitter and/or receiver for the antenna. This contrasts with a passive electronically scanned array (PESA), in which all the antenna elements are connected to a single transmitter and/or receiver through phase shifters under the control of the computer. AESA's main use is in radar, and these are known as active phased array radar (APAR). The AESA is a more advanced, sophisticated, second-generation of the original PESA phased array technology. PESAs can only emit a single beam of radio waves at a single frequency at a time. The PESA must utilize a Butler matrix ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radar Cross-section
Radar cross-section (RCS), also called radar signature, is a measure of how detectable an object is by radar. A larger RCS indicates that an object is more easily detected. An object reflects a limited amount of radar energy back to the source. The factors that influence this include: *the material with which the target is made; *the size of the target relative to the wavelength of the illuminating radar signal; *the absolute size of the target; *the incident angle (angle at which the radar beam hits a particular portion of the target, which depends upon the shape of the target and its orientation to the radar source); *the reflected angle (angle at which the reflected beam leaves the part of the target hit; it depends upon incident angle); *the polarization of the transmitted and the received radiation with respect to the orientation of the target. While important in detecting targets, strength of emitter and distance are not factors that affect the calculation of an RCS becaus ...

Nizhny Novgorod Research Institute Of Radio Engineering
The Nizhny Novgorod Research Institute of Radio Engineering (NNIIRT) is a Russian electronics company specializing in the development and manufacturing of radar equipment. It is a subsidiary of the Almaz-Antey group. History Founded in 1947, NNIIRT is based in the city of Nizhny Novgorod. Beginning in 1975, NNIIRT developed the first VHF 3D radar capable of measuring height, range, and azimuth to a target. This effort produced the 55Zh6 'Nebo' VHF surveillance radar, which passed acceptance trials in 1982. In the post–Cold War era, NNIIRT developed the 55Zh6 Nebo U 'Tall Rack' radar, which has been integrated with the SA-21 anti-aircraft weapons system. This system is deployed around Moscow. In 2013, NNIIRT announced the further development of the 55Zh6UME Nebo-UME, which combines VHF and L band The L band is the Institute of Electrical and Electronics Engineers (IEEE) designation for the range of frequencies in the radio spectrum from 1 to 2 gigahertz (GHz). This is a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
S-300 Missile System
The S-300 (NATO reporting name SA-10 Grumble) is a series of long range surface-to-air missile systems developed and operated by the former Soviet Union, now fielded by the militaries of Russia and Ukraine as well as several other former Eastern Bloc countries. It was produced by NPO Almaz, based on the initial S-300P version. The S-300 system was developed to defend against air raids and cruise missiles for the Soviet Air Defence Forces. Subsequent variations were also developed to be able to anti-ballistic missile, intercept ballistic missiles. The S-300 system was first deployed by the Soviet Union in 1979, designed for the air defence of large industrial and administrative facilities, military bases and control of airspace against enemy strike aircraft. During the 2022 Russian invasion of Ukraine, Russian invasion of Ukraine in 2022, military analysts have stated that Russia has modified a number of systems to perform surface-to-surface missile, surface-to-surface strikes. ...

S-400 Missile System
The S-400 Triumf (russian: link=no, C-400 Триумф – Triumf; translation: Triumph; NATO reporting name: SA-21 Growler), previously known as the S-300 PMU-3, is a mobile, surface-to-air missile (SAM) system developed in the 1990s by Russia's NPO Almaz as an upgrade to the S-300 (missile), S-300 family. The S-400 went into service on 28 April 2007. The first battalion of the newest surface-to-air missile systems assumed combat duty on 6 August. Development The development of the S-400 system began in the late 1980s and was announced by the Russian Air Force in January 1993. On 12 February 1999 successful tests were reported at Kapustin Yar in Astrakhan, and the S-400 was scheduled for deployment by the Russian army in 2001. Dr. Alexander Lemanskiy of Almaz-Antey was the Chief Engineer on the S-400 project. In 2003, it became apparent that the system was not ready for deployment. In August, two high-ranking military officials expressed concern that the S-400 was being t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Nebo-M
The Nebo-M or Nebo-ME (in Cyrillic: 55Ж6МЕ «Небо-МЕ», Nebo means "sky") also known as RLM-ME or 55Zh6ME (export version) is an integrated multi-functional radar system that features a multiple programmable multi-band design radars and a central data fusion. The radar began to be investigated in 1984. The radar complex is made up of a command post module and one to three different radars which are deployed on separate 8x8 24-ton trucks. The manufacturer claims this radar system can detect 5th generation aircraft like the F-22 and F-35 and detect long-range ballistic missile launches. Nebo-ME is an export version with some degraded characteristics. History System design was initiated on a mobile chassis in 1999, after NATO countries attacked the Federal Republic of Yugoslavia, in which the stealth F-117 participated - one was shot down by S-125 Neva with help of P-18 radar - Russia started to perceive stealth aircraft as a possible future threat to their security.
