【Chinese Satellites Go "Invisible" in Space, Leaving U.S. Radar "Blind"】
A U.S. Space Force official said that China and Russia are developing satellite stealth technology in the space domain, making it more difficult for ground radars and telescopes to detect their satellites.
According to a report on the "The Drive" website on December 11, U.S. Space Force General Lutch revealed that in recent years, a "cat-and-mouse" game has been taking place in geosynchronous orbit, with U.S. and Chinese and Russian space satellites tracking each other. In the past year, this game of hide-and-seek has become even more intense.
Lutch also gave a specific example: three "Shiyan-24" series satellites stationed in low Earth orbit moved synchronously. These three satellites have different radar cross-sections. The second one (B satellite) is smaller than the first one (A satellite), and the third one (C satellite) is even smaller. Lutch admitted: There's no doubt that China is advancing satellite stealth technology, which is also something the U.S. has been researching for a long time.
Lutch further stated: Since 2012, China has invested a great deal of effort in satellite stealth technology, continuously testing ways to make small satellites harder to detect, and they may have already succeeded. The People's Liberation Army published a research paper in 2022 and demonstrated the test results: a micro-metal satellite named "Olive-B" had a shape like a "sphere," and it was continuously tested in an anechoic chamber.
The U.S. Space Force assessed that this micro-metal satellite is not only difficult to detect with the naked eye or telescopes but also significantly reduces its radar cross-section, posing a greater challenge to the U.S. "anti-satellite" technology.
