This is a medium-to long-range tactical 3D surveillance radar the primary function of which is air defence, and can expected to be deployed in regional air defence networks. 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. Coverage: (Pd=0.9, Pfa=10-6, SW1, σ = 3m2) Azimuth 360º Elevation: 0º~20º Search range; 320km Height: 25,000m Target capacity: ≥72 tracks Antenna: Beams: 8 vertically stacked / 1st sidelobe -30db Detection Accuracy (rms): Range: 90m Azimuth: 0.2º Height: 400m @ 200km Target Resolution: Range: 300m Azimuth 0.9º Elevation 1.0º Reliability: MTBF: ≥4150hrs MTTR: ≤30mins MTI improvement 40dB System noise figure 5.5dB IF bandwidth 450Hz This radar employs a number of modern technologies including a low-sidelobe antenna, pulse compression, self- adaptive moving target indication (AMTI), with a peak envelope power (PEP) of approximately 1MW. 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. RF agility range is stated to be 15%, which suggests about 450MHz in the highest RF range listed. There is a selection of 30 RFs within this range available for diversity or agility operations, which suggests repetitive fixed frequency hopping in the latter case. At least one source states that the frequency diversity interval is 150MHz, which might confirm the use of the two lower frequency sub-bands. |
