- W1987703231 abstract "The performance of matched-field processing algorithms in shallow water, in the presence of soliton packets, has been investigated through analysis of data from the SWARM 95 experiment. In particular, acoustic data collected with a vertical array and a moving up-sweep source have been analyzed, in the frequency range 275–350 Hz. The source was placed below the surface mixed layer and its distance from the array varied between 2.5 and 27 km. Source localization using the conventional and minimum variance matched-field algorithms has been performed, in order to assess the robustness of these processors in the presence of environmental mismatch and their degradation as a function of range. The primary result of the analysis is that both processors fail to localize the source accurately, even at the shortest range (2.5 km). Although broadband processing and inclusion of corrections for the array tilt improved the results, the errors in source range (of the order of 1 km at short ranges and 5 to 10 km at long ranges) and depth remain significant. The performance of other matched-field processors is currently investigated." @default.
