The Nebo-SVU (also known as 1L119) (in Cyrillic: Небо-СВУ, 1Л119) is a very high frequency (VHF) multi-functional radar and the first radar with an active electronically scanned array (AESA) antenna operating at meter wavelengths. The radar was introduced in 2001 as a replacement for the Nebo-SV.
The Nizhny Novgorod Research Institute of Radio Engineering (Russian acronym: NNIIRT) has since 1948 developed a number of radars. [7]Other innovations were radars with frequency hopping; the P-10 Volga A (NATO: KNIFE REST B) in 1953, radars with transmitter signal coherency and special features like moving target indicator (MTI); the P-12 Yenisei (NATO: SPOON REST) in 1955, as well as the P ...
The Nebo-M [1] or Nebo-ME (in Cyrillic: 55Ж6МЕ «Небо-МЕ», Nebo means "sky") also known as RLM-ME or 55Zh6ME (export version) [2] 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.
These were mainly radars in the VHF-band, and many of which featured developments in technology that represented "first offs" in the Soviet Union. Innovations include the first Soviet air surveillance radar with a circular scan: the P-8 Volga (NATO: KNIFE REST A) in 1950, the first 3D radar : the 5N69 Salute (NATO: BIG BACK) in 1975, and in ...
Nebo-SV/S Nebo-M Air surveillance radar Over 50 Soviet Union Russia: Plans to have 100 complete by the end of the 2010s. [295] Nebo-M counter-stealth radars are being supplied since 2017. [296] As of 10 May 2024 at least 2 have been lost in the Russian Invasion of Ukraine. [55] 9S18 Kupol: Target acquisition radar Unknown Soviet Union Russia
Radio waves are defined by the ITU as: "electromagnetic waves of frequencies arbitrarily lower than 3000 GHz, propagated in space without artificial guide". [5] At the high frequency end the radio spectrum is bounded by the infrared band. The boundary between radio waves and infrared waves is defined at different frequencies in different ...

Very high frequency (VHF) is the ITU designation [1] 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 ...
