The study investigated observer tactical target detection and identification performance on displays of downward looking infrared imagery collected at 500-, 1,000-, and 2,000-foot altitudes. Six male college students were tested individually under all three altitude conditions. To balance out learning effects, a change-over design was used to vary the order of altitude presentations from subject to subject. The different altitude presentations for each subject were spaced a week apart to minimize learning effects. There were 24 target site locations containing a total of 62 individual targets. The five target types used were vehicles, helicopters, missiles, botas, and bridges. An implication from the study is that a relatively high degree of target detection and identification performance can be expected on a display of pictorial-type imagery in which the scene takes as little time as 4 seconds to move across the display screen.
