Paper Abstract

In this paper, beam scintillation effects on the illumination of targets are quantified with respect to human observer performance. The theory of man-in-the-loop target acquisition is reviewed along with the principles of operation of an actively illuminated gated incoherent imager. A model to account for the effects of beam scintillation on target acquisition performance is introduced. A simulation of beam propagation was developed and used to apply a nonuniform illuminating field to a series of monochrome images of targets. These images were then used in a perception experiment with trained observers. The results of these perception experiments compare well with predictions from the model.
