Abstract : To explore the effects of target load, duration of tracking time, and tracker proficiency upon tracking performance in the Missile Master system, trackers of high, average, and low rated proficiency were required to track real targets on operational tracking consoles. Tracking performance during six contiguous 10-minute periods was recorded photographically. The number of targets assigned to be tracked varied from 3 to 18 for the six periods. Accuracy indexes were computed--percentage of instances trackers' 'tags' were found on target and number of targets tracked with perfect accuracy in relation to number assigned. No statistically significant differences in tracking performance were found among groups differing in rate proficiency nor across time periods. Within 10-minute periods, a small decrement in mean accuracy score was found. Mean accuracy score and mean percentage of targets tracked with perfect accuracy decreased as target load increased. However, the average number of targets tracked with perfect accuracy increased with increased target load. Individual trackers were found to differ appreciably in performance. (Author)
