Experiments were designed (1) to develop and validate a training program for using the acoustic sensor to identify vehicles in convoy; (2) to provide estimates of operator performance in identifying vehicles using the acoustic sensor; and (3) to investigate the effect of different sensing concepts and bandwidths on the operator's ability to identify vehicles. Following an orientation and procedure training, 18 school-trained, unattended ground sensor (UGS) operators were tested in their ability to identify military vehicles in convoys. Magnetic tape recordings simulated use of the acoustic remote sensor in the field. Two sensing concepts were incorporated--continuous, wherein the operator monitors the entire convoy, and intermittent, wherein the operator hears each vehicle in the convoy for 4 seconds. Operators then received vehicle recognition training that used concepts of immediate feedback, self-scoring, paired comparisons, and practice. Following this training, the operators were retested to measure the effects of the training. An exploratory study compared operator performance using three bandwidths: 50-1500 cps, 50-2000 cps (presently used), and 50-4000 cps. Operators varied widely in ability to identify individual vehicles in convoys. The best operator reported twice as many correct identifications as did the poorest operator, under some conditions.
