A camouflage having attenuating properties within the infrared and microwave ranges consists of a water-based foam having an expansion ratio greater than or equal to 1000, and/or a plastic-based foam having an expansion ratio greater than or equal to 100. The camouflage is particularly, but not exclusively, useful to conceal vehicles, antitank mines, airfields and stationary objects, such as coast artillery pieces and trench shelters. In generating such camouflage, vehicle engine cooling air may be utilized to blow the foam. |
