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.56
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-70 Lena-M with chirp signal modulation in 1968.8
