History

Founded in 1947, NNIIRT is based in the city of Nizhny Novgorod.[2]

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.[3]

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.[4]

In 2013, NNIIRT announced the further development of the 55Zh6UME Nebo-UME, which combines VHF and L band radars on a single assembly.[5][6]

NNIIRT designed air surveillance radars

The Nizhny Novgorod Research Institute of Radio Engineering (Russian acronym: NNIIRT) has since 1948 developed a number of radars.[7] 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 1982 the first VHF-band 3D-radar; the 55Zh6 Nebo (NATO: TALL RACK).

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-70 Lena-M with chirp signal modulation in 1968.[8]
