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.
Claims14
A camouflage structure comprising:
- a first layer reflecting in the IR range with an emissivity which has a different course in the atmospheric windows II (3-5 μm) and III (8-14 μm), wherein the emissivity in the atmospheric window II has a falling tendency with increasing wave length.
A camouflage network comprising:
- a camouflage structure with a layer reflecting in the IR range with an emissivity which has a different course in atmospheric windows II (3-5 μm) and III (8-14 μm), wherein the emissivity in atmospheric window II has a falling tendency with increasing wave length.
