Abstract
To ensure that a camouflage structure will not lose its effectiveness even in changing temperatures (day/night, sunshine/clouds) when protecting against reconnaissance in the IR range, the camouflage structure features varying emissivity tendencies in the atmospheric windows II (3-5 um) and III (8-14 um). In other words, the emissivity in the IR range is not constant and at a certain level, but it has an increasing or decreasing tendency in at least one selected spectral range.
