Abstract:

The problem of specification of dwell time is set in the context of its implications for operational effectiveness. Two studies are presented which investigated the effect of eleven dwell times, five noise levels and two target types upon the probabilities of detection and identification of aural radar target signals. These studies were conducted through the use of simulated radar watch programs synthesized from taperecorded X-band returns and presented binaurally via headphones. It is concluded that dwell times as short as one-eighth second can be tolerated if only vehicular targets are of interest, but that at least one-half second dwell time is necessary if personnel targets are to be considered. Noise level is found to affect performance more for personnel than for vehicular targes. Details of circuitry and experimental design are presented. Author
