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 ...
However, unlike the NNIIRT, this design bureau focused on higher frequency radars like the P-20, P-30, P-30M, P-35, P-32D2 and the P-50 (NATO: E/F-bands). These radars have better accuracy and faster scan rates, and are thus more suited for ground control of fighter aircraft, which complement the lower frequency radars developed by the NNIIRT ...
As a system, Nebo-M is a complex which features different radars. From the beginning, Nebo-M represented a modification and modernization of older VHF band Nebo SVU, L-band Protivnik G, and S/X-band Gamma S1 radars on mobile chassis. The designations of the newer variants are RLM-S, RLM-D, RLM-M, and the command post KU-RLK.

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.
