VISUAL SEARCH AND DETECTION UNDER SIMULATED FLARE LIGHT.
Abstract
Preliminary laboratory research on methods for evaluation aerial flare sources and for optimizing their placement are described. Ten subjects performed target acquisition (detection and recognition) tasks under simulated flare light and ten, serving as controls, under simulated daylight conditions. Generally, target acquisition required an average of approximately 90 seconds under four simulated Mark 24 flares dropped 0.25 mile apart and ignited at 2,000 feet, compared with an average of about 15 seconds under simulated sunlight (simulating those light conditions characteristic of a partly cloudy day). Target location contributed significantly to response times. There were no statistically significant differences in response times between the two types of targets used (trucks and antiaircraft weapon sites). (Author)
