The use of full wavefield (matched field) processing techniques in a multipath environment is illustrated. Experimental data consist of the arrivals at a hydrophone array from an explosive source in shallow water. A coherent recombination of the multipath arrivals is performed in order to provide enhanced signal-to-noise ratio for source detection and range/depth localization. Thus, signal-to-noise ratio is enhanced. Range/depth localization information is made available by searching for a peak in the surface formed by plotting beamformer output at all range/depth cells of interest. The results are compared to theoretical predictions of range/depth localization resolution based on the characteristics of the oceanic waveguide
