PLAAF for the surveillance Radar in Tibet.
Radar Cover – Two Radar Regiments (RRs) have been deployed by PLAAF for the surveillance of Tibet and South Xinjiang region. These regiments cover the flights from the mainland and monitor Indian air activities along the Sino- Indian border. Medium and high level cover in TAR is fairly good. Considering the elevated locations of the PLAAF radars, it is quite likely that movement of Indian strike aircraft may be picked up well before they enter Tibet air space.
Types Of Radar, Pics and Information
ECRIEE / CETC JYL-1 Long-range 3D Air Defence Radar
The JYL-1 radar is carried in the 2004 CRIA listing of Chinese indigenous products.
The JYL-1 is a long-range 3D surveillance radar typical of those assets that might be found in a modern air defence network.
It functions in the E/F-band region and might be used as either a military or commercial asset for air traffic control and management purposes.
Coverage: (Pd=80%, Pf=10-6, SW1, RCS=2m2)
Azimuth 0º ~ 360º
Elevation: 0º ~ 25º
Search range; 320km
Measurement Accuracy (rms):
Height: 600m @ 200km
MTBF: ≥ 800hrs
MTTR: ≤ 0.5 hrs
In the long-range search mode, max PRF to be expected is approx 430pps.
CETC YLC-18 High Mobility Medium Range Low Altitude 3D Radar
his is a two-vehicle convoy, high mobility, medium-range, low-altitude 3D radar announced by CETC in June 2007 at Singapore.
The reported system features are excellent low-altitude performance with high measurement accuracy, strong ECCM capability.
Operating frequency: EF-band
Coverage: (Pd = 80%, RCS = 2m2)
Range: ≥ 250km
Height: ≥ 12,000m
Elevation: 0º ~ 35º
Azimuth: 0º ~ 360º
Its detection range suggest instantaneous PRF of 600pps thus operational PRF of approx 400 is suspected.
Measurement accuracy: (rms)
Azimuth: ≤ 0.3º
Range: ≤ 100m
Height: ≤ 600m (within 200km)
Assembly/disassembly: 20mins/4 persons
MTBCF: ≥ 1,000 hrs
MTTR: ≤ 30 mins
In view of its 3D capability and potential to control aircraft and surface-to-air weapons, its likely frequency cover is shown, which is within the ITU regulated bands.
Besides having Surveillance Radars PLAAF and PLA deployed SAM radars which have range of 150-200kms..
