The radar is built to MIL-STD-1553 standard so it is compatible with western electronics and weaponry. Originally, the radar is capable of simultaneously tracking 10 targets (later to be upgraded to 15) and engaging 2 (later to be upgraded to 6) of the 10 tracked when using semi-active radar homing air-to-air missiles , or 4 of the 10 tracked ...
Diagram of AN/SPY-3 vertical electronic pencil beam radar conex projections. X band functionality (8 to 12 GHz frequency range) is optimal for minimizing low-altitude propagation effects, narrow beam width for best tracking accuracy, wide frequency bandwidth for effective target discrimination, and the target illumination for SM-2 and Evolved Sea Sparrow Missiles (ESSM).
The Distant Early Warning (DEW) Line, constructed in the late 1950s, was reaching obsolescence in the 1980s.With the signing of North American Air Defence Modernization agreement at the "Shamrock Summit" between Prime Minister Mulroney and President Reagan in Quebec City on 18 March 1985, the DEW Line began its eventual upgrading and transition becoming the North Warning System (NWS) of today.
The Nebo-M [1] or Nebo-ME (in Cyrillic: 55Ж6МЕ «Небо-МЕ», Nebo means "sky") also known as RLM-ME or 55Zh6ME (export version) [2] is an integrated multi-functional radar system that features a multiple programmable multi-band design radars and a central data fusion. The radar began to be investigated in 1984.
The SPY-6 system consists of two primary radars and a radar suite controller (RSC) to coordinate the sensors. An S-band radar is to provide volume search, tracking, ballistic missile defense discrimination, and missile communications, while the X-band radar is to provide horizon search, precision tracking, missile communication, and terminal illumination of targets.
