Abstract : The study was primarily designed to compare single versus dual-sensor displays on the basis of observer target detection and recognition performance. Strip imagery from downward-looking infrared (IR) and side-looking radar (SLR) of the same ground path was dynamically displayed to three 12-man groups of Strategic Air Command radar observers. One group viewed only the IR display, a second group viewed only the SLR display, and the third group viewed both displays simultaneously. The observers were asked to find and identify airfields, freeway cloverleaves, railroad yards, tank farms, and power transmission lines, on the 11 by 11-inch displays. The imagery was displayed at a scale of 1:23,700 (1 inch = 1/3 mile) and at a simulated ground speed of 300 knots. The observers were scored on the number of targets detected, the number of nontargets they called targets, and the screen distance objects traveled before being responded to. (Author)
