Acoustic Source Propagation And Localization In The Norfolk Canyon
The accuracy of the backpropagation method in localizing a low frequency harmonic point source in the highly variable shallow waters of Norfolk Canyon is demonstrated. The method is implemented using the implicit finite difference solution to the wide angle parabolic wave equation. The results indicate the advantage of using coherent signal processing with a wide aperture array, and an acoustic propagation algorithm which can accommodate accurate complicated oceanographic data.
