  • Passive acoustic bearing estimation via ultra short baseline wideband methods
    Patent number: 9383428
    Abstract: In various embodiments, a passive bearing detector is disclosed. The passive bearing detector comprises a plurality of hydrophones. The plurality of hydrophones is arranged in a three-dimensional geometry. The three-dimensional geometry exposes each of the plurality of hydrophones to an ambient aquatic acoustic environment. The passive bearing detector further comprises a processor electrically coupled to the plurality of hydrophones. The processor is configured to determine a direction of arrival of an unknown broadband acoustic signal received by the plurality of hydrophones based on the phase difference of the unknown broadband acoustic signal at each of the plurality of hydrophones.
