The positional accuracy of aircraft radar targets as displayed in an air traffic control airport surveillance radar system ASR-4 was sought as one of the inputs essential for determining aircraft separation standards. Using radar track input from the Atlantic City, New Jersey, ASR-4, the radar targets of two test aircraft executing flight patterns of varying relative spacing were photographed as displayed in both beacon and primary radar modes on scan- converted and PPI displays. The displayed positions were related to simultaneous precision track from single-target instrumentation radars EAIR and TAIR to derive error measures for range, azimuth, and separation. The extensive analysis program employed a least-squares analysis of variance.
