Abstract : Target detection performance on a radar and sonar task was assessed as a function of time on watch for two display conditions. In one condition, the display alternated between radar and sonar sensors every four minutes; in the other condition, the radar and sonar sensors were displayed in a conventional, non-alternating, manner. Comparison of the data obtained under the alternating and non-alternating radar display conditions revealed no differences in performance between conditions but declines in detection performance as a function of time on watch were evident under both conditions. Detection performance on the sonar display benefited from the display alternation during the second half of the main watch. (Author)
