Analysis of ASW Contact Classification Procedures

Abstract

ASW contact classification operations are analyzed as a two-step process. In the first step, a classification 'system,' which includes the sonar operators, reduces the multivariate sonar input information to one of a simpler set of 'observations.' In turn, these observations are used by a 'decision maker' in selecting the classification category. The systematic transformation of information is described by a 'receiver operating characteristics' (ROC). A rational way of using the ROC in decision making is to apply a 'maximum decision rule' which ensures that the resulting risk is not greater than the least upper bound of all of the possible risks in the given situation. The value of the system is defined as the difference between the maximum risk obtained when the system is not used and the maximum risk obtained when the system is used.
