Multi-spectral camouflage

Multi-spectral camouflage is the use of techniques to conceal objects from detection by methods across several parts of the electromagnetic spectrum; while traditional camouflage attempts to hide an object in the visible spectrum, multi-spectral camouflage also deals with hiding the object from detection methods such as infra-red, radar, and millimetre-wave imaging at the same time.

Applications
Multi-spectral camouflage can be applied to individuals in the form of a ghillie suit, disguising the heat given off by the wearer's body, and to vehicles and buildings with either specialised paints or camouflage nets that reduce the amount of heat given off by an object, as well as altering the shape and size of its radar signature.
