A major goal of designers of active sonar systems is to obtain longer target detection ranges. One consequence of longer ranges is longer time intervals between transmissions. Another is lower signal-to-noise ratios and thus fewer transmissions that produce perceptible echoes from a target. The purpose of the study was to investigate the effects of these variables on operator target detection performance. The results indicated the desirability of history or memory type displays with long-range sonar systems to enhance operator detection performance. Author
