A site-specific photographic camouflage arrangement and method for making the same are provided. The site-specific photographic camouflage arrangement includes a digital photographic image and distorting disruptive patterns placed on the digital photographic image to create visual confusion to disguise the recognizable form of a camouflaged object by breaking up its outline.

Exemplary embodiments of the present disclosure provide a system, apparatus, and methods for producing a high-performance camouflage and thermal management composite fabric textile systems. The systems comprise woven and non-woven composite fabrics consisting of layers for thermal and electromagnetic wave propagation as well as human thermal emission control. The systems incorporate thermal plastic insulation, felt insulation, electromagnetic wave absorption materials, electromagnetic wave propagation and thermal emission control elements, and camouflage pigment patterns. Dots containing encapsulated metallic particulates enable omni-spectral electromagnetic wave and thermal radiation signature manipulation and control as well as cost-effective manufacturing. Single blended textile processed via needle punching produces hair/fur-like protrusions made from a multilayer fabric composition having EM wave and thermal radiation control elements. The protrusions subsequently contain EM propagation and thermal emission control elements on their surfaces for omni-spectral camouflage and detection mitigation. The systems expand the options for meeting the demands of today and future stealth missions.

A system and method for changing the exterior color of a vehicle is disclosed. The system includes a vehicle with a color change system integrated into the vehicle body of the vehicle. The color change system can change the color of a portion of the vehicle body in response to commands from a color change module running on a computing system within the vehicle. The color change module can detect information about the vehicle's environment to determine an appropriate target exterior vehicle color that contrasts substantially with the vehicle's environment.

The present disclosure relates to a visible and infrared stealth element. The element of the present disclosure may selectively control thermal radiation energy according to a wavelength, and may also control a surface color and reflectance of near-infrared light and short-wavelength infrared light.

A dynamic thermal infrared stealth composite material based on dual phase change is a VO.sub.2/mica-based phase change thermal storage thin layer composite material composed of a VO.sub.2 nanoparticle coating and a mica-based phase change thermal storage thin layer, wherein the mica-based phase change thermal storage thin layer consists of stearic acid and a vanadium-extracted mica substrate in a mass ratio of 3-5:5-7. The composite material based on dual phase change is prepared by extracting vanadium from vanadium mica using a roasting and acid leaching process to prepare VO.sub.2 nanoparticles and a vanadium-extracted mica, embedding a phase change functional body into the vanadium-extracted mica as a support substrate to prepare a mica-based phase change thermal storage thin layer, and coating the VO.sub.2 nanoparticles on the mica-based phase change thermal storage thin layer. The dynamic thermal infrared stealth composite material can synergistically reinforce thermal infrared stealth performance.
