Description

Technical field [0001] The invention relates to the technical field of military stealth, in particular to a visible-infrared compatible stealth device. Background technique [0002] Stealth technology (also known as target characteristic signal control technology) is a technology that controls the signal characteristics of the target to make it difficult to be found, identified, and tracked. Stealth technology is for detection technology, including visible light stealth, infrared stealth, radar stealth, laser stealth, and acoustic stealth. With the continuous advancement of science and technology, various photoelectromagnetic detection technologies have also developed rapidly. The threat to traditional combat weapons has become more and more serious. It has reached the level of "discover and destroy", and higher stealth technologies have been proposed. The requirements of multi-band compatible stealth has become the mainstream. [0003] Visible-infrared compatible stealth means t...
