Abstract:

This report presents the results of a study to determine the feasibility of a sonar range prediction system based on a graphical presentation of profiles of expected range. The effects of changes in gradient and layer depth on expected range were studied. Two BT classification systems were studied to determine their application to a range prediction system. Because the gross features of the classification systems and the uncertainties of range prediction models, it is concluded that a range prediction system such as the type studied here is not feasible at this time.
