Abstract:

The study investigated the hypothesis that sequential changes of background color on a simulated radar display enhances target detectability. Two experiments were conducted wherein target detectability was assessed in terms of the accuracy in which subjects determined the presence of a randomly appearing target symbol imbedded in visual noise. The first experiment tested 30 subjects to determine the relative detectability of targets among display backgrounds of homogeneous color and backgrounds presenting abrupt changes of color. The second experiment tested 24 subjects to determine if the speed andor sequence of background color change affected target detectability. Results of the study showed that homogeneous green or blue backgrounds significantly enhanced target detectability when compared to the sequentially changing colored background, and that speed and sequence of background color change have little effect. The study also showed colored backgrounds to enhance target detectability when compared to the conventional method of radar display. Author
