The Effect of Predesignation Information Upon Target and Checkpoint Recognition Performance

摘要

A simulation study was performed to investigate a new display technique for improving air-to-ground target recognition performance. This technique, called target predesignation, indicates to the pilot the anticipated location of a target on any cockpit sensor display. In this manner the pilot, by searching the presdesignated area on his cockpit sensor display, has a reduced area in which to search for the target. In the study several parameters of the predesignation technique were investigated in a fixed-case simulation in which Marine Corps pilots and radar operators served as subjects. Results clearly indicate that visual target recognition performance can be markedly improved by the presentation of dynamic target predisignation information. Results for radar target recognition, although not statistically significant, suggests that radar target acquisition can be improved by the addition of predesignation information. Total results are not as definitive in providing information on the optimal configuration of the predesignation display. (Author)
