A camouflage material with wide-band effect ranging from the visible portion of the spetrum, the IR region of the spectrum from 1 to 20 micrometers, as well as the radar region from 3 GHz to 3,000 GHz, consisting of at least a base layer with a vapor deposited metallic reflecting layer having a surface resistivity of 0.1 to 10 ohms per square and a camouflage paint layer applied thereon, the pigments of which have reflectivity that is similar, in the visible and near infrared portions of the spectrum, to that of the natural background, for example, to chlorophyll. In order to insure that such a camouflage material provides secure protection against detection by thermal imaging apparatus, even in the far IR region of the spectrum, without reducing the protective effect in the visible and near IR region of the terrestrial thermal radiation as well as in the radar region, the camouflage paint contains a binder that has good transparency in the spectral regions of the atmospheric windows II (3-5 .mu.m) and III (8-14 .mu.m). The camouflage material can be used for camouflage nets and thermal insulation mats which, together with means for providing removal of hot gases, can constitute a suitable camouflage system for military targets in which heat is produced by internal combustion engines.
A camouflage material having a wide-band effect ranging from the visual portion of the spectrum up through the radar region of the spectrum, said material comprising at least a base layer, a homogenous metal layer on said base layer reflective in the range of terrestrial thermal radiation as well as in the radar region of the spectrum and having a specific surface resistivity of not more than 0.5 to 10 ohms per square and a camouflage paint applied on said reflective metal layer, said paint containing pigments having reflective properties in the visible and near IR spectral regions that are similar to the natural background and containing a binder having high transparency characteristics in the spectral regions of the atmospheric windows II (3-5 .mu.m) and III (8-14 .mu.m) and wherein the emissivity of the camouflage paint in windows II and III varies over the surface of the material and varies between 50 and 90% in window II and between 60 and 95% in window III and wherein the metal is selected from the group consisting of aluminum, copper, zinc and its alloys.
A thermal insulation mat comprising two sheets of a camouflage material having a wide-band effect ranging from the visible portion of the spectrum up to the radar portion of the spectrum, said material having a metal layer which is reflective in the range of terrestrial thermal radiation and a camouflage paint applied on said reflective layer, said paint containing pigments having reflective properties in the visible and near IR spectral regions that are similar to the natural background, the sheets being joined together along one edge of each sheet and being arranged so that one overlies the other and the said camouflage paint being applied to an outer surface only of each sheet.
