  • Patent number: 11726196
    Abstract: Sonar systems and related methods are provided. A sonar system includes a transducer array having a transverse axis and a longitudinal axis disposed perpendicularly thereto. A processor is operative to associate signals with a plurality of transducers in the transducer array so as to form a first acoustic beam, which propagates in a beam first direction and has a first beam width in a first transverse plane. The first transverse plane extends along the beam first direction and contains the transverse axis of the transducer array. A beam spreading device having a curved surface is positioned relative to the transducer array such that the first acoustic beam impinges on the curved surface. Following impingement on the curved surface, the first acoustic beam propagates in a beam second direction and has a second beam width in a second transverse plane. The second beam width is greater than the first beam width.

  • Patent number: 11668823
    Abstract: A system is provided for imaging an underwater environment. The system includes a transducer assembly with at least one transmit transducer element and an array of receive transducer elements. Each receive transducer element is configured to receive sonar returns and form sonar return data. A sonar signal processor is configured to receive the sonar return data from each receive transducer element and generate sonar image data. The sonar return data from all of the receive transducer elements may be summed and used to form a high-definition 1D (e.g., time-based) sonar image. The sonar return data from only a subgroup may be summed and used to form a lower-definition 1D sonar image. In some systems, an array of series-connected transmit transducer elements can be used. The orientation of the emitting faces of the array may vary slightly to mimic a curved surface for increased beam coverage.
