Abstract
The phenomenon of polarisation causes smooth man-made objects, such as metal and glass, to have a different polarisation signature to that of natural vegetation. Therefore, polarisation has the potential to discriminate man-made objects from background clutter. Polarimetric information, combined with conventional thermal imaging, provides a powerful means of reducing false alarms in applications such as situational awareness, detection of low signature targets and disturbed earth. The paper presents results of discriminative imaging algorithms that were designed to augment polarimetric signatures. Recent results from a LWIR polarimetric imager are presented and these show the merit of discriminative imaging techniques when applied to polarimetric thermal imagers.
