Research was undertaken to determine if an auxiliary magnified display would aid radar-reconnaissance operators in recognizing unbriefed targets. Two identical parallel-driven side-looking radar films were presented on a dual-screen rear projection console to 36 radar navigator-bombardiers from the Strategic Air Command. Subjects assigned to the control group viewed imagery on a 7-inch square main screen. Subjects assigned to each of the three treatment groups used a cross-hair location device, which permitted any portion of the imagery on the main screen to be presented on an upper 7-inch-square auxiliary screen, at 2x, 4x, or 8x magnification. The imagery traveled from the top to the bottom of the main screen at a simulated aircraft speed of 658 knots, depicting, at a scale of 1417,000, a strip of terrain 40 nautical miles wide. Providing an auxiliary magnification display had no beneficial effect upon the number of targets correctly recognized, the number on nontargets mistaken for targets, the proportion of responses that were made to real targets, or upon response latency.
