Abstract

Several processors are developed and used to perform source localization on the 3250-km San Diego-Hawaii path of the Acoustic Engineering Test (AET). Associated simulations an done to test the range-frequency limits of coherent matched-field processing using PE modeling through a simulated internal-wave environment. The AET experiment is presentlywell beyond the range of effective coherent matched-held processing. A mode filter was developed to extract 60 complex made amplitudes fromthe data received on the 20-element vertical line array. A mode spacedepth estimator successfully localizes the source. A mode arrival time difference range estimator is developed and found to be biased by internal-wave induced mode coupling. The final processor developed utilizes the stability of early arriving wavefronts to determine the sourcerange by matching wavefront arrival patterns. (C) 1998 Acoustical Society of America.
