Target Detection and Identification Performance on Infrared Imagery Collected at Different Altitudes.
Abstract
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.
