RADAR SYMBOLOGY STUDIES LEADING TO STANDARDIZATION,
Abstract
The report covers initial studies directed toward standardization of basic symbols representing 'enemy,' 'friendly,' and 'unknown' targets on a radar scope. College students of both sexes and enlisted military men served as subjects. In Experiment I, subjects assigned and ranked 68 geometric designs within the three meaning categories. Experiment II studied retention values after a short exposure to these same forms. Experiment III required all subjects to design a code differentiating the three meaning categories. All significant findings on meaning were highly dependent on pictorials. Perceptual differentiation and ease of learning are recommended as the major dimensions of code design. (Author)
