Abstract
The purpose of this study was to determine if the utilization of filters would improve target identification performance on a television display. Inflight video tape was obtained of convoys of vehicular targets under different meteorological visibility conditions while using two types of filters and a no-filter condition on the television camera. The video tape was used in the laboratory for dynamic presentations on a television display. Analysis of variance revealed with five miles visibility no reliable difference in target identification slant ranges between filters 15 and 29, but reliable differences between filter 15 and no filter, and between filter 29 and no filter. With seven miles meteorological visibility reliable differences in target identification performance were found between all combinations of the conditions investigated. Maximum mean improvements in performance were as follows: with five miles visibility filter 15 increased target identification range 2600 feet farther than the no-filter condition. With seven miles visibility filter 29 increased target identification range 3685 feet feet farther than the no-filter condition.
