Abstract
A polarization thermal sensor is presented that has ability to detect manmade objects even when there is little or no thermal contrast, or when the object is obscured by clutter or vegetation. Imagery will be shown for scenarios in which polarization contrast remains high during periods of zero thermal contrast. Also, data will be presented that shows the detection of manmade targets in natural clutter, long after thermal equilibrium of the target with the background has been established.
