Improved Search and Scan Technique for Short Range Air Defense Crewmen

摘要

U.S. Army Short Range Air Defense (SHORAD) systems require visual detection of threatening aircraft prior to initiating engagement procedures. This thesis evaluates alternative visual search techniques which employ scan patterns derived from an understanding of SHORAD capabilities, the tactical air threat, and human visual search phenomena. An experiment was conducted to determine the overall effectiveness of each technique. Analysis of experimental data suggests that one pattern is significantly more effective than other patterns currently in use. Recommendations are also made to improve SHORAD visual search effectiveness by adopting specific training programs.
