U.S. Spy’s Secrets Assist Chinese Electronic Warfare Against U.S. military Data Links

 

 

” China’s military is using stolen U.S. military secrets obtained from a convicted spy to defeat a high-technology communications system used in joint warfighting, combined arms warfare, and missile defenses, according to U.S. officials.

The disclosure that China has the capability of jamming the Joint Tactical Information Distribution System, or JTIDS, was revealed in a Chinese military technical article published in July.

JTIDS is part of a group of military communications systems called Link 16 that gives U.S. military forces jam-resistant communications, a key strategic advantage used in joint warfighting, a specialty of the American military.

JTIDS allows for a nearly unlimited number of military commanders and operators to share information, such as precision location or position data, critical in tracking, monitoring, and targeting. It is also resistant to electronic warfare attacks by rapidly jumping to different frequencies.

The Chinese article reveals that the People’s Liberation Army is studying this feature and working to defeat it.

The article, “Anti-Jamming Performance of JTIDS-Type Waveform,” was published July 10 in the journal Aerospace Electronic Warfare, a publication of Institute 8511, a unit of the China Aerospace Science and Industry Corporation (CASIC).

The article states that Chinese researchers have studied the JTIDS anti-jamming capabilities and formulated an “optimal jamming strategy from the point of view of the interferer.” “
