Abstract
An apparatus includes at least one transmitter configured to transmit wireless signals that create different localized heating in different portions of a scene. The different localized heating in the different portions of the scene is based on different moisture or liquid content within objects in the scene. The apparatus also includes at least one controller configured to control the at least one transmitter in order to control the different localized heating in the different portions of the scene and to create a desired thermal radiation pattern in the scene. The desired thermal radiation pattern in the scene may include a camouflage pattern that increases clutter in an infrared image, at least one temporary infrared marker, or at least one false shape in an infrared image. The desired thermal radiation pattern could reduce a contrast between a cold infrared background in the scene and one or more targets in the scene.
