Matched-field localization with many uncertain environmental parameters: experimental data results

Matched-field source localization methods can be sensitive to environmental parameter mismatch. In this paper, a source localization method which is robust to environmental parameter uncertainty is presented. This method allows for a family of propagation models based on the uncertainty intervals of the environmental-parameters. It is a computationally efficient approximation to a full maximum-likelihood search which can be followed by a local exact maximum-likelihood search. The effectiveness of this method is demonstrated using experimental data from the Mediterranean Sea
