MOONLIGHT I. IDENTIFICATION OF STATIONARY HUMAN TARGETS
Abstract
The studies were conducted to determine low visibility identification curves for human targets as a function of: (1) Level of illumination, (2) position of target, (3) Position of observer, (4) Night vision training of observer. Two experiments were conducted using four groups of basic trainees as subjects. The first experiment was conducted under no-moon illumination and the second, using the same subjects, was conducted under full moon. The variables in each experiment were (1) position of target (standing, kneeling, or prone), (2) position of observer (standing, kneeling, or prone), and (3) type of night vision training administered to each group (classroom training, field training, a combination of classroom and field training, or no training). It was concluded that the ability to identify human targets under low natural illumination is: (1) Directly related to level of illumination, (2) Directly related to size of target being observed, (3) Directly related to height of the observer's eyes above the ground under full-moon conditions, but not under no- moon conditions, (4) Not related to the short periods of night vision training employed in these studies.
