IR Polarimetric Signatures

摘要

Infrared polarization relies on surface temperature, roughness, material properties, aspect angle to the sensor, sky down-welling and background radiance reflecting from the target. Often times, the polarization signature of a manmade target is different than the surrounding background. Furthermore, that difference is often present even when the thermal signature of the same target blends into the background. This paper will present maritime, airborne and ground data sets of polarization signatures of several objects that allow detection when other methods fall short.
