ABSTRACT:
A system shields IR emissions from remote sensors and has a flexible outer metallic layer extending to cover objects emitting IR energy on the covered ground. The outer layer is conductive of heat energy and faces upward. A flexible inner metallic layer coextensively extends adjacent to the outer metallic layer. The inner layer is conductive of heat energy and faces downward. Spaced-apart thermo electric chips are between and in contact with the outer and inner layers. The chips transfer heat energy between the outer and inner layers. A sensor of IR radiation on ambient ground provides signals representative of the thermal signature of the ambient ground. A controller couples signals to the chips in response to the representative ambient ground thermal signals for controlling the heat energy radiated from the outer layer to match the radiated IR signature from the outer layer to the IR signature of the ambient ground.
