Abstract : The experiment grew out of a suggestion that color might be used to indicate doppler in a passive sonar display. A fast approaching target would appear as red, a slower approaching target as yellow. A slowly receding target would appear as green, a fast receding target as blue. A total of 152 men searched for 4 sec for a sloping line of dots of a single color embedded in a background of dots of various colors. Each group of men performed only a single condition. Test methods and performance are reported.
