Abstract : Progress in the development of an experimental electronic unit that would aid in sonar target classification is discussed. The aid is a small, special purpose computer which uses clues from an active sonar of the modified SQS-4 (SQS-29 through SQS-32) type to make classification decisions. The classification aid is functionally divided into three parts: the input units, the output display unit, and the logic unit. The input units are three in number, one for each type of sonar output display: audio, graphic, and PPI. Each unit has twenty-five clues associated with its push buttons. The output display unit contains two types of displays, one for the intermediate answers, and one showing the final probabilistic answer. The logic unit contains the logic circuitry and the power supplies needed for the entire system.
