SOURCE TRACKING IN THE HUDSON CANYON EXPERIMENT

摘要: In the Hudson Canyon experiment, a broadband source, transmitting simultaneously in four frequencies, moved range at constant depth and bearing. Using matched-field processing we demonstrate that source can be localized tracked. Incoherent approaches for processing, based on averaging of ambiguity surfaces obtained with narrowband Bartlett Minimum Variance processors, are compared to new coherent variant. Localization is very successful when either incoherent or estimator used. The processor performance determining location poor case but improves significantly introduction scheme.
