INFRARED SIGNATURE MATCHING SYSTEM, CONTROL CIRCUIT, AND RELATED METHOD

An infrared (IR) signature matching system comprises a heating and cooling device, a plurality of sensors configured to detect information related to the IR signature of the heating and cooling device and a background environment, a controller operably coupled with the heating and cooling device and the plurality of sensors. The controller is configured to receive the information from the plurality of sensors and adjust the temperature of the heating and cooling device until the IR signature of the heating and cooling device and the IR signature of the background environment are at least substantially matched in a selectable sub-region of the IR spectrum. Other systems, control circuits and related methods for matching IR signatures and cloaking objects in the IR spectrum are disclosed herein.
