  • Patent number: 10725149
    Abstract: Systems and methods are disclosed for autonomous joint detection-classification of acoustic sources of interest. Localization and tracking from unmanned marine vehicles are also described. Based on receiving acoustic signals originating above or below the surface, a processor can process the acoustic signals to determine the target of interest associated with the acoustic signal. The methods and systems autonomously and jointly detect and classify a target of interest. A target track can be generated corresponding to the locations of the detected target of interest. A classifier can be used representing spectral characteristics of a target of interest.
    Type: Grant
    Filed: January 12, 2018
    Date of Patent: July 28, 2020
    Assignee: Ocean Acoustical Services and Instrumentation Systems, Inc.
