Single-Hydrophone Localization.

摘要

By 'localization' we mean the problem of determining the location of sound in the ocean by use of hydrophone data. Single-hydrophone localization methods are those that use data from only one hydrophone. Serious research in localization may be said to have begun with Bucker's matched-field technique in 1976, although as Clay has pointed out, experiments by Parvulescu and Clay had shown, a decade earlier, that localization was a feasible problem. Most research in localization has, following Bucker, used continuous wave (cw) sources, whereas the Parvulescu-Clay experiments led to techniques that are perhaps more easily understood in the time domain. The literature of cw localization is now quite large, and a review of the subject is beyond the scope of this paper. Interesting recent cw work, incorporating sophisticated signal-processing techniques, is presented by Fizell and Baggeroer et al. Here, we are most concerned with the time-domain single-hydrophone technique of Clay as implemented by Li and Clay. Keywords: Reprints. (KR)
