Abstract

A crucial point in multipath ocean acoustic tomography (MOAT) is to associate the estimated time delays to acoustical paths in order to make a correct geophysical inversion. The authors propose a theoretic tool to solve the problem of ray identification in term of probabilistic data association and find the theory suitable to be used on a real data tomography experiment for which the classical tools were inefficient because of a large quantity of unresolved and unstable paths. It promises some useful results for future tomography experiment made in difficult acoustic conditions
