This paper provides a model of target acquisition that will aid in the design of electro-optical detection devices. Twelve subjects, highly skilled in target detection, located targets in 32 terrain scenes taken from a realistic terrain board. Independent variables included display resolution, field of view, target contrast, target range, number of targets, and scene complexity. All experimental variables had a significant effect on target detection performance. A regression equation is presented, which can be used to predict detection time given the various sensor, target, and scene characteristics.
