ABSTRACT:
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.
