Abstract : This report presents the results of an Institute Research and Development (IR and D) project in the field of Antisubmarine Warfare (ASW). The objective, as it was finally defined, was to develop and apply an analytic tool for the investigation of the ASW contact classification problem. A computer simulation model was developed for the purpose of generating the evaluation clues commonly used in the contact classification procedure. These clues, singly and in combination, are then used to accumulate point value totals in eighteen categories. After a series of pings, linear weighting factors are applied to these numbers to arrive at a single weighted point value that is used to determine the contact classification. A separate program has been developed to generate optimized coefficient values for the linear weighting equation. Large numbers of submarine and nonsubmarine contacts may be evaluated, and the frequency distributions of the weighted point values in these two categories may be automatically plotted through the use of another computer program. Detailed validation of the simulation model was beyond the scope of this study, however follow-on work and more intensive analysis has been proposed to the Navy. FORTRAN listings of the various computer programs are included, and typical results for a small sample of contacts are presented. (Author)
