Abstract

Spatial radiance variations, when combined with sensor or scene motion, have been recognized as a significant source of clutter for staring infrared surveillance sensors. In this paper, data acquired using the NASA Daedalus multi-spectral scanner is examined. On three flights of this airborne high resolution and large extent sensor system, a variety of earth background scenes was collected. Significant spatial radiance variations were measured in mountainous and agricultural earth backgrounds. Data was also collected to allow quantification of the radiance gradient at important interfaces such as between cloud and terrain.
