Determining if Sonar Contact Can be Maintained

ASW effectiveness is strongly dependent on whether sonar contact can be maintained long enough for a attack to be accomplished. Proper design and use of weapons systems both depend upon the probable duration of contact maintenance. A number of stochastic models of propagation and detection variability are considered. A method is described of fast-time tactical simulation which makes use of such models to evaluate the overall effectiveness of the sonar/weapon system combination.
