Abstract
We examine a matched-field processor for source localization that combines measured data with parabolic equation (PE) starting fields to backpropagate an ambiguity surface outwards from a vertical line array. For an N-element system, this (unnormalized) processor generates the ambiguity surface N times faster than the standard Bartlett correlator. The effectiveness of the backpropagation algorithm is assessed by comparing it to the Bartlett processor for multi-tonal data obtained during the Hudson Canyon experiment.
