Two experiments were performed to appraise a conventional polar coordinate 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.
