China Unveils Strange Device to Find Invisible Objects

China is outpacing the world in robotics production, building safer alternatives to uranium reactors, and flooding the globe with high-tech electric vehicles — to name just a few of the rising superpower's achievements. But the country is also innovating on the military front — a domain usually thought to be dominated by the United States. Researchers at the 38th Research Institute of China Electronics Technology Group Corporation recently announced the successful development of a handheld device they say can detect cloaked stealth fighters. The new bit of kit blends civilian telecoms tech with military-grade radar sensitivities according to the South China Morning Post, a Hong Kong-based newspaper. The researchers claim that it can detect stealth signals at a rate of "100 percent." Here's how it works: US stealth vehicles use a system called low-probability-of-intercept radar (LPIR) to operate virtually undetected. LPIR makes military hardware nearly untraceable by employing sever ... Read full article.
