The feasibility of generalized approaches to training military personnel in the use of different types of sonar/acoustic warfare systems was explored. The initial phase of the project consisted of the analysis of representative sonar and acoustic equipment to identify training areas and operator performance requirements that could be subjected to generalized training methods. The degree of commonality in operator tasks, skill, and knowledge requirements for each system was considered. Phase 2 involved the evaluation of existing training methods. A high degree of commonality was found in operator tasks for surface and subsurface systems involving stimuli of low to moderate uncertainty, procedure following, and simple motor responses. The application of generalized training concepts was judged feasible for sonar operators, although further research is needed on the exact approaches to be taken. (DGC)
