Abstract : The overall program objective is to determine the feasibility and applicability of an antisubmarine warfare search director concept for use in developing optimal search tactics and sonobuoy drop patterns to detect and localize submarines. The concept makes use of negative information that the target has not been detected up to the present time by deployed sonobuoys. As areas are searched by each sonobuoy and the target is undetected, the probability that it is in searched areas decreases whereas the probability that it is in unsearched areas increases. A dynamic display of this probability density map over the expanding uncertainty areas shows where the target might be at any time and, indicates where the next sonobuoys should be dropped.
