Description: The SBI-16 Zaslon, 'Barrier' in English, is an state-of-the-art, long-range, passive phased array antenna radar system developed by the former Soviet Union for its Mig-31 high-speed interceptor. The Zaslon radar features the ability to search, detect, identify and track airborne targets in the forward and tail hemispheres using electronic scanning technology in both look-up and look-down modes. The radar's flexibility allows for operation in single or group modes sharing target information via a built-in data-link among four Mig-31s or with another three air defense fighters such as Mig-23, Mig-29 and Su-27. A group of four Mig-31s covers an area of 800 kilometers wide and 2,000 kilometers long. When operating in groups a single Mig-31's radar is enough to provide target data to the other aircraft with their radars being off. The radar system can operate in the presence of adverse weather and active and/or passive jamming as well as interacting with ground control systems and airborne early warning and control (AEW&C) aircraft.

The Zaslon was developed by V.Tikhomirov Scientific Research Institute of Instrument Design (NIIP) in the late 1970s entering into service in the early 1980s onboard the Mig-31 interceptor. Around 500 radar units were produced for the Mig-31 which became the first aircraft equipped with a phased array radar location station (RLS) until the 2000s. The radar enables the Mig-31 to detect and engage airborne targets flying at altitudes between 50 to 28,000 meters utilizing R-33E, RVV-AE and R-73 air-to-air missiles. The maximum detection range is 200 kilometers against a bomber-sized target in the forward hemisphere and 35 kilometers in the rear hemisphere against a fighter-sized target. Besides, the Zaslon can detect an aircraft based upon the heat radiation at a distance of up to 56 kilometers. Operating as a pulse Doppler radar it can cover +/- 60-degree in azimuth and +/- 35-degree in elevation. The basic Zaslon is able to track up to 10 targets engaging four of them.
