Patent ID: 7102814

Claim:
A system for shielding IR emissions from remote sensors comprising: a flexible outer metallic layer extending to cover objects emitting IR energy on ground covered thereby, said outer metallic layer being conductive of heat energy and facing in an upward direction toward the sky; a flexible inner metallic layer coextensively extending adjacent to said outer metallic layer, said inner metallic layer being conductive of heat energy and facing in a downward direction toward said covered ground; a plurality of spaced-apart thermo electric chips between and in contact with said outer metallic layer and said inner metallic layer, said thermo electric chips transferring heat energy between said outer metallic layer and said inner metallic layer; a sensor of IR emissivity and temperature on ambient ground for providing signals representative of the thermal signature of said ambient ground; and a controller coupling signals to said thermo electric chips in response to said representative ambient ground thermal signals for controlling the heat energy radiated from said outer metallic layer.
