Variance in radiance recorded from heterogeneous targets in the optical-reflective, middle-infrared, and thermal-infrared regions

Abstract

In this paper, the variance in radiance recorded from heterogeneous scenes in the optical-reflective, middle- IR, and thermal-IR regions is considered. The impact of this variance on feature discrimination is considered. Equations are presented, by which the efficacy of standard analytical techniques for given feature mapping tasks may be evaluated using available data. It is also suggested that these equations maybe helpful in development of mission-oriented sensors.
