China Advances Signals Intelligence

Kimberly Underwood

For the terminal decade, “informatization” of its national civilian together with armed services infrastructure has been a superlative priority for the People’s Republic of China. The country’s efforts to leave of absence a global might inwards information together with communications technology scientific discipline include a focus on signals intelligence. Out of its $150 billion full defense forcefulness budget, the province is spending an estimated $15 billion on signals intelligence, said David Stupples, professor of electronic together with radio systems, City, University of London, at an August nine Association of Old Crows (AOC) online event. Not surprisingly, mainland People's Republic of China has the almost extensive signals news (SIGINT) capability of whatever province inwards the Indo-Pacific region. With increasing tensions inwards the South mainland People's Republic of China Sea, China’s pregnant armed services presence is supported yesteryear “unprecedented levels of SIGINT activity,” Stupples noted. The professor ventures that, inwards particular, mainland People's Republic of China is preparing a major SIGINT facility on Woody Island inwards the Paracel Islands to “give Beijing an unprecedented reconnaissance overview” of the South mainland People's Republic of China Sea region. 

In addition, mainland People's Republic of China operates several dozen SIGINT Earth stations in-country “and elsewhere,” to monitor signals from Russia, Taiwan, Japan, South Korea, Republic of Republic of India together with Southeast Asia, every bit good every bit signals from U.S. armed services units operating inwards the region. mainland People's Republic of China likewise is constructing satellite Earth stations inwards Argentine Republic together with Republic of Chile to procedure large amounts of data, Stupples said.

A large SIGINT facility amongst satellite communications (SATCOM) intercept facilities located on Hainan Island—just due south of China’s mainland—primarily monitors surface area U.S. naval activities, every bit good every bit international communications satellites, Stupples said. For the Indian Ocean region, the province has increased SIGNINT activeness through investments inwards the port together with land-based facilities, establishing considerable SIGINT capability, he emphasized.

“Additionally, the Chinese accept developed a serial of SIGINT collection surface vessels that monitor U.S. armed services operations together with exercises inwards Far Eastern seas, together with subsurface SIGINT collection vessels together with sensors to monitor bounding main lanes, specifically the Silk Road,” Stupples shared.

Of almost concern, however, is China’s integrated maritime SIGINT system, Stupples said. “Data collected from acoustic sensing buoys, surface SIGINT vessels, satellites together with ‘underwater gliders’ is streamed to news centers inwards the Paracel Islands,” he stated. Moreover, to proceed an oculus on Guam, mainland People's Republic of China has installed acoustic sensors inwards the Mariana Trench together with on Yap Island for reconnaissance on U.S. surface together with subsurface naval activity. 

As for trying to teach SIGINT access to the United States, “historically, China’s challenge has been the lack of straightaway access to satellite downlinks into the [region],” Stupples said. The professor ventured that inwards the belatedly 1990’s Republic of Cuba began providing mainland People's Republic of China amongst access to major SIGINT sites at Bejucal, but westward of Havana, run yesteryear Cuba’s Directorate of Military Intelligence. “Defectors claim Havana likewise operates covert SIGINT sites from its Washington-based Interests Section together with from its diplomatic facility at the United Nations,” he added.

Furthermore, mainland People's Republic of China is advancing its aircraft-based SIGINT. It has xxx electronic warfare planes, including 11 aircraft used for electronics intelligence, every bit good every bit a growing divulge of airborne early on alert together with command planes. “These aircraft are beingness pose to function inwards the South mainland People's Republic of China Sea together with off the coasts,” Stupples said.
