SEOUL (MI) : A South Korean company claims that it has
developed a radar absorbing material (RAM) suited to absorption of
almost all frequencies.
Cony International, based in Icheon, announced it has developed a RAM with reflectivity lower than -10dB at any frequency.
“The
Cony RAM has greater radar absorbency at almost all frequencies,” said
Choi Jae-chul, chairman of the company. “This material could be applied
to many types of weapons systems, such as fighter jets and warships, for
stealth capabilities. It will help improve their survivability and
mission capability to a greater extent.”
Korea Maritime and Ocean
University evaluated the Cony RAM for its radar cross-section efficiency
last November. The absorption rate peaked at a level as high as 98
percent, according to the university.
The national university in
Busan is one of the two organizations in South Korea to evaluate the RAM
performances. The other is the Agency for Defense Department,
affiliated with the Ministry of National Defense.
“RAM generally
absorbs radar waves either at a certain frequency or a short range of
frequencies,” said Professor Kim Dong-il of the Department of Radio
Sciences and Engineering at the university. “But the Cony RAM has been
tested to have excellent electromagnetic absorption performance over a
wide band.”
The RAM could be used in developing a stealthy fighter
jet, Kim said, referring to the country’s KF-X project aimed at
developing an F-16 class aircraft with radar-evading stealth
capabilities.
Established in 1986, Cony International has long
developed microwave absorbing materials both for commercial and military
purposes.
In the late 1980s, the company supplied the South Korean Navy with RAMs for warships to resolve electromagnetic interferences.
It also signed a contract with a Middle East nation in 1992 to provide RAMs for fighter aircraft.
