Impulsive Source Localization in Shallow Water Using Single Hydrophone

doi:10.3969/j.issn.1000-1093.2012.09.019

Abstract

Abstract: Aimed at coherent multipath structure of the underwater acoustic channel in shallow water, a method of impulsive source localization using a single hydrophone was proposed. The phase change properties of reflected wave at different acoustic interfaces were studied. The difference between surface reflection and bottom reflection was used to solve position ambiguity in the location equation. The estimated resolutions of amplitude attenuation and phase change of the underwater acoustic channel were improved by using projection onto convex sets, compared with match filter. The localization error using single hydrophone was estimated with the error propagation equation. The experiment results show that this method is feasible in shallow water environment, and has the advantages of simple structure and low cost.
