Abstract
Abstract : A-745(*surface targets, target acquisition), (*target discrimination, performance(human)), range(distance), performance(human), terrain, velocity, probability, predictionsasars(army small arms requirements study), army small arms requirements studyA study of target detection times for human targets in various field situations was conducted to obtain data for the Army Small Arms Requirements Study (ASARS). Three significant variables--terrain complexity, target speed, and target distance--and two randomized control variables (direction of movement and starting position) were studied. Results indicate that terrain complexity and target range were positively related to detection time; target speed was negatively related. Examination of the 24 detection-time distributions suggests that the underlying probability distribution for the detection-time distributions was not exponential in form.
