Abstract : Two experiments were performed to appraise a conventional polar coorinate display modified to present bearing, range, and height information. The display consisted of a PPI surrounded by an annulus. Each target was represented by two blips on the same bearing: the inner blip on the PPI gave bearing and range, and the outer blip in the annulus gave bearing and height. The display was a synthetic or simulated display. Engineering modifications actually to reproduce bearing, range, and height information on this PPI were not accomplished. The purpose of this appraisal is psychological one: to determine how accurately a man can understand and extract information from a display of this sort. (Author)
