The Effect of Simulated Sun Angle on Air-to-Ground Target Acquisition.
Abstract
The purpose of this study was to determine the effect of sun angle on target acquisition by an airborne observer. The experiment was conducted according to a three-by-two repeated measures design, representing three simulated sun angles (0, 90, and 180 degrees with respect to the observer) and two terrain locations (hilly and flat). Three groups of ten subjects were asked to detect tank targets on a 1000:1 terrain table at both terrain areas. The test started at a maximum simulated slant range of 8500 feet and was reduced by 500 footsteps during each successive 30-second trial until a correct target detection occurred. The results of the tests are given and discussed.
