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 ...
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.
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 P-18PL [6] [7] is a modernized Polish road-mobile, long-range, three-dimensional (3D), very high frequency (VHF) early warning radar with an active electronically scanned array (AESA) technology. The radar is particularly remarkable for its enhanced anti-stealth capability and is somewhat similar to the Russian Nebo-SVU radar. Key features:
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 ...
Radar-frequency bands according to IEEE standard [17] Band designation Frequency range Explanation of meaning of letters; HF: 0.003 to 0.03 GHz: High frequency [18] VHF: 0.03 to 0.3 GHz: Very high frequency [18] UHF: 0.3 to 1 GHz: Ultra-high frequency [18] L: 1 to 2 GHz: Long wave S: 2 to 4 GHz: Short wave C: 4 to 8 GHz: Compromise between S ...
P-14MA/5H84AMA [7] – ground-based long-range VHF surveillance radar P-180U is offered as the modernized follow-on to its prototype, the analogue P-14. Produced in LiTak-Tak [ 8 ] ( Lithuania ). Modernization of early-warning VHF radar 5N84A (5N84, 44Zh6 or P-14) offers the best (in terms of efficiency/cost ratio) alternative to restoration or ...
