Abstract:

An experimental program to determine the capabilities of a man-computer system in processing target-in-noise displays is described. A general detection model, based on digital processing and a time varying operator display of the type found in sonar systems, is discussed. The theoretical effects of a number of detection model parameters are analyzed and their implications for the human operator explored. An experimental study of human operator processing of simulated Time-Bearing data under varying signal to noise ratios SN and clipping thresholds T are described. Results indicate that human operators can maintain a consistently high detection performance level over the range of SN and T studied. Performance, as measured by the number of trials to reach a decision, follows the theoretical optimum predicted by analytical studies. Author
