Abstract : A study was conducted for the systematic determination of the effects of various sensor parameters and environmental variables on the capability to identify target materials. The approach incorporated an experimental program of data collection and laboratory target signature measurements together with the development of a unique data analysis scheme. Targets were illuminated with a Krypton laser that produced visible light simultaneously in four spectral channels (0.65 micrometers, 0.57 micrometers, 0.52 micrometers, and 0.48 micrometers). The 1.5-watt beam, having a divergence of 1.6 mrad, was scanned horizontally across an existing test range. The primary target was a calibrated series of painted panels of various sizes, colors, and orientations. Parameters studied included gain, bandwidth, scan speed, field of view, color contrast, and surface moisture. Atmospheric transmission and background illumination were measured.
