Three experiments were conducted to determine the effect of variations in signal-to noise (S/N) ratio and increases bandwidth on the ability of remotely monitored operators using the acoutic sensor to identify vehicles in convoy. In general, the operator was to discriminate between the following seven military vehicles traveling in typical convoys: jeeps, gamma goats, 2-1/2-ton trucks, 5-ton trucks, 10-ton trucks, armored personnel carriers, and tanks. Targets were presented at each of four levels of S/N ratio: +6 decibels (dB), +12 dB, +18 dB, and +24 dB. The operational bandwidth of 50-2000 hertz (Hz) was compared to that of 50-4500 Hz. Special training under all of the above conditions was given. The results indicate that operator identification completeness declines as the S/N ratio decreases approximately 1% per 1.5 dB of S/N ratio. No differences were found in use of the two bandwidths. Use of automatic gain control should be limited because the operator uses loudness variations to discriminate among targets. (Author).
