Abstract

Sustained attention or operator vigilance is required in the detection of critical signals that occur infrequently and at irregular intervals over a prolonged period. In this paper, we review some methods for mitigating the vigilance decrement for an auditory sonar monitoring task. These methods pertain to enhancing the saliency of sonar targets for situations when the operator may be required to monitor multiple displays, listen to competing sound sources, attend to distractions, and cope with ambient noise. Enhanced target saliency is expected to assist in maintaining operator efficiency via increasing detection rate and decreasing detection latency of auditory sonar targets. This should lead to tactical superiority of sonar operators in the continuing threat of underwater warfare.
