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.
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 ...
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 ...
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.
