OVERVIEW: The JY-11B is a self-propelled, low-altitude, 3D air surveillance radar, operating in the E/F-band.
DETAILS: The JY-11B employs ‘reconfigurable’ transmission beams and Digital Beam Forming (DBF) for reception to provide low-altitude and good sea-surface detection, with modern processing techniques including AMTI and pulse Doppler sampling. Unlike the JY-11, this is not a dismountable system but the antenna can be raised on a hydraulically controlled tower to improve the system’s low altitude coverage, very similar in concept and design to the German TRM-S system, or ByeloRussian Vostok E. It also features a high degree of automation, giving it both a fast reaction and standalone capability. It can also provide target designation services to weapon systems.
