The small dummy targets used in this study are adequate for use in a subsequent tactically realistic aerial observer field test. The larger dummy targets used in this study were recognized as dummies sufficiently often that modifications increasing their fidelity were required. The observer debriefings provided specific information on which to base subsequent modifications. Apparent target size square mil size, which is a function of slant range distance, angle of observation and actual target size, significantly affected the accuracy of target identification and discrimination. As apparent target size increased, accuracy of target identification and of target discrimination increased. Prior aerial observer experience and training was significantly related to the accuracy of target identification. Observers with prior aerial observer experience and training were significantly more accurate in identifying the targets than observers who had no prior aerial observation experience or training.
