Description
The Raduga 2 was an autonomous secondary surveillance radar that operated in the lower L-band at 837.5 MHz and the UHF band at 740 MHz. Developed in the early 1990s in cooperation with Siemens, it had a peak power of 12 kW, an instrumented range of 400 km, and an accuracy of 150 m in range and 0.3° in azimuth, with a beamwidth of 3.3°. It supported both the Russian national standard (УВД) and the Western European Mark X (RBS) for interrogation, but due to its lack of Mode S support, it was subsequently replaced by the MSSR Krona.
