EFFECTS OF DISPLAY WIDTH ON SIDE-LOOKING RADAR TARGET RECOGNITION.
Abstract
An investigation was made of the effect of display screen width on the recognition of targets of opportunity on a moving strip of rear-projected side-looking radar imagery. The imagery moved across the screen from left to right at a simulated aircraft speed of 1316 knots. The screen height was a constant 18 inches and the screen widths were 4.5, 9, 18, or 36 inches. The image scale was 1:70,700 (one inch equals approximately one nautical mile). Increasing screen width, hence increasing the length of time objects appeared on the display, has no beneficial effect upon the number of targets correctly recognized or upon the number of nontargets mistaken for targets. Response latency increased as a linear function of display width. (Author)
