Passive Localization of Multiple Sources Using Widely-Spaced Arrays With Application to Marine Mammals

Abstract

The long-term goal of our research is to develop algorithms that use widely spaced hydrophone arrays to localize and track multiple unknown sound sources, possibly in shallow-water environments, over long distances. By developing methods to simultaneously track multiple vocalizing marine mammals, we hope to contribute to the fields of marine mammal bioacoustics, ecology, and anthropogenic impact mitigation.
