Abstract:

The report describes a simulation research study which measured the effects of target size, target-to-background contrast, television raster scan line orientation, and display viewing angle on both target detection and target identification using television. One hundred twenty different simulated air-to- surface target attacks against buildings on a three-dimensional terrain model were video tape-recorded using a 525-line television system. These attacks were then shown to 16 subjects whose tasks were to detect the target from its background and to identify it from a number of alternatives shown on briefing photographs. Performance measures were slant range at correct detection SRD, slant range at identificatioN SRI, and probability of correct identification PCI.
