<Kanwa News January 20, 2003> Western sources claim that
China has imported 4 sets of KOLCHUGA passive radar systems from Ukraine.
China obviously intends to reinforce its capability of "striking stealth
aircraft" in "the new three strike and three defense" campaign. Traditionally,
Ukraine is the main source for the Chinese military to obtain radar
Earlier, China imported ST68UM from Keiv and used it on the earlier
version of S300PMU SAM for surface-to-air search. The import of KOLCHUGA
may have a great deal to do with China's own program to develop stealth
aircraft detect radar. On the internal publications of the Chinese military,
there have been more emphasis on the importance of detecting stealth
aircraft, particularly the application of passive detect technology.
It is also stressed that some cryptic and mobile radars should be established
and at the same time use ultra-low or ultra-high frequency radar, multi
radar systems and passive track and positioning systems to deal with
the stealth aircrafts of the enemy.
KOLCHUGA uses passive radio-electronic environmental monitoring stations.
Normally, a monitoring system consists three such stations. The three
antennae integrate the VHF, UHF and SHF monitoring bands, which are
capable of detecting and analyzing the signals at 0.1-19 GHz band. The
monitoring range of the station is from 150km to 600km, covering a region
of 45 degrees within 200km, 8 degrees within 600km. The three antennae
of the radar systems are set up in an overlapping format, with a distance
of 45km in between. One of the radar systems is installed on a 6-wheeled
truck. KOLCHUGA can also be linked with the ground-to-air missile system,
and is capable of transmitting the information of the stealth target
to the ground-to-air missile system in advance. KOLCHUGA is manufactured
by the Ukraine POPAZ United Enterprise. Kanwa>
