Abstract
Abstract A multispectral three-dimensional camouflage mat has a base or substrate layer into which are woven strands of yarn of varying length and color to simulate terrain or landscape, or alternatively to serve as a decoy by simulating a target. Desired reflection and absorption of visible light as well as infrared, ultraviolet, and microwave frequencies is provided by materials integrally contained within the yarn strands, and by supplemental materials on the base layer. An alternative embodiment is a light-penetrable camouflage screen which also uses the concept of integral incorporation of reflecting and absorbing additives for nonvisual wavelengths in plastic material forming the body of the screen.
