Multi-spectral camouflage is the use of counter-surveillance techniques to conceal objects from detection across several parts of the electromagnetic spectrum at the same time. While traditional military camouflage attempts to hide an object in the visible spectrum, multi-spectral camouflage also tries to simultaneously hide objects from detection methods such as infrared, radar, and millimetre-wave radar imaging.

Among animals, both insects such as the eyed hawk-moth, and vertebrates such as tree frogs possess camouflage that works in the infra-red as well as in the visible spectrum.

Generally, an object’s characteristic signature is understood as a set of data that enables clear detection and/or identification of the object. For example it is possible to determine from the signature whether the object in question is an ordinary vehicle or an armoured car. In addition it is also possible to identify the type of object, e.g. the type of vehicle or armoured car. In the five spectral ranges mentioned earlier, i.e. VIS, NIR, MIR, SWIR and RADAR, the characteristic signature consists of different measured variables:

• in the visual range: colours and shape of the object
• in near and shortwave infrared: spectral reflectivity and shape
• in the thermal infrared: characteristic shape and arrangement of warm or hot parts of the object
• in the radar range: the characteristic spatial or angular distribution of the reflected radar signal
