Abstract : An experiment was performed to measure the accuracy with which observers could estimate the separation (distance apart) of two aircraft targets as displayed by continuous film strips of current operational terminal radar equipment. Experimental materials consisted of scan-by-scan photos of two types of display devices: a plan position indicator (PPI) and a scan-converted PPI. Two types of target or aircraft radar returns were used--primary radar echoes and beacon transponder (secondary radar) returns. Two types of separation were employed; i.e., aircraft separated mainly in the range dimension and targets separated principally in the azimuth dimension of the display. Eighteen observers with varying degrees of radar experience made approximately 1,600 judgments of target separation. (Author)
