Abstract
The present invention provides a smart material with radar and infrared integrated stealth effect, comprising: a first transparent base material; a second transparent base material opposite to the first transparent base material, and the first transparent base material and the second transparent base material There is an interlayer between the transparent substrates; a transparent solution storage connected to the interlayer; a vacuum device connected to the interlayer; the non-opposite surfaces of the first transparent substrate or the second transparent substrate are provided with infrared Stealth material; the infrared stealth material is formed by stacking multi-layer films; the multi-layer film includes alternately arranged YbF3 films and ZnSe films whose thicknesses are respectively a quarter of the central wavelength. Compared with the prior art, the present invention injects and extracts a transparent solution with a different dielectric constant from the substrate in the sandwich structure to realize the switch function for radar waves; a one-dimensional quasi-periodic structure infrared stealth material layer is arranged on the surface of the substrate, and its It has the characteristics of non-destructive transmission of radar waves, so as to achieve the effect of integrated radar and infrared stealth.
Description
technical field [0001] The invention belongs to the technical field of radar stealth materials, and in particular relates to an intelligent material with radar and infrared integrated stealth effect. Background technique [0002] In the modern warfare system, the importance of infrared stealth, radar intelligent stealth and multi-spectrum full-spectrum stealth has become increasingly prominent, seriously affecting the survivability and penetration capabilities of weapons and equipment. Weapons and equipment that do not have the above stealth performance will be difficult to survive in the future war system, let alone achieve effective strikes against the enemy. Therefore, it is very important to design smart materials with radar-infrared integrated stealth characteristics and radar intelligent control stealth characteristics to improve the survival and penetration capabilities of weapons and equipment. Contents of the invention [0003] In view of this, the technical prob...
