OVERVIEW: The JY-14 GREAT WALL Radar is a long-range, 3-D surveillance and interceptor control radar operating in the E/F Band.

DETAILS: The JY-14 is primarily used in national air defense system.  It is capable of tracking over 72 contacts.  The JY-14 is reported to have a range of anti-jamming facilities, to ensure normal operation in the most severe of electronic warfare (EW) environments.  It has 8 RF feeds, six in E/F-band and two in D-band, the latter two giving good height cover where the lowest may also be used for an IFF facility.  This radar employs a number of modern technologies including a low-sidelobe antenna, pulse compression, self-adaptive moving target indication (AMTI).
