Résumé
Target detection using passive electro-optic devices operating in
the 8-14pm band is often limited by background clutter. A
possible method of overcoming this limitation may be to use the
polarisation content of the image to discriminate between man
made targets and naturs. background. In this paper laboratory
measurements are presented of the polarisation state of 10-6pm
radiation reflected from. and emitted by, a range of materials.
It is concluded that elliptical polarisation is not of primary
importance and that measurements of the degree of linear
polarisation appear to provide useful discrimination between
man-made objects and *natural' ones.
