title: Estimation of source range using horizontal multipath in continental shelf environments.
abstract: A method to estimate source range in environments that exhibit three-dimensional propagation effects is presented. A hybrid modeling technique using vertical modes and horizontal rays is employed. Results are obtained in a computationally efficient manner and require limited knowledge of the environment. The method is applied to data recorded on a horizontal line array located 12 km east of the southern coast of Florida. The results show an average error of 3.7% in estimating the range of an acoustic source located 20 to 63 km away from the array.
