Abstract : Sixteen Air Force navigators were tested, after appropriate training, on four strips of side-looking radar imagery. The imagery, at a scale of 1: 197,000, moved across a back-lighted 14- by 14-inch screen at 3.3 inches per minute - corresponding to 500 knots. The subject's task was to identify all airfields, bridges, tank farms, power lines and railroad yards. The speed and accuracy of locating and identifying these targets under four different levels of briefing were assessed. The four briefing levels were: none, 10 minutes study of the corresponding chart prior to the simulated flight, access to the chart during but not prior to the flight, 10 minutes study of the chart prior to the flight and access to it during the flight. Fifty-six percent of the targets were correctly identified. On the average the target traveled 3.1 inches (56 seconds) after first appearing on the screen before being identified. False positive responses averaged 30%. The briefing levels compared, however, had no significant differential effects on the speed and accuracy of identifying targets or on the number of false positives. It suggests that new briefing techniques and materials will need to be developed. (Author)
