Satellite stealth technology occupies a unique position in the space attack and defense system. It has certain similarities with the stealth technology applied on ground armored vehicles, warships, and aircraft. However, due to the different satellite development conditions and the space environment, satellite stealth technology faces greater challenges in its research and application. The requirements and conditions of satellite stealth technology were summarized on the basis of satellite engineering application. The international cutting-edge stealth technology was systematically reviewed. This research focuses on radar stealth methods, and infrared and visible light stealth methods. The technical bottlenecks and future prospects of satellite stealth were discussed, in the aim to promote the application of stealth technology on satellites.
