摘要： 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.

摘要： A sonar system is provided including a sonar assembly configured to attach to a motor assembly of a watercraft or a watercraft. The sonar assembly includes sonar transducer element(s) that transmit sonar beam(s). The sonar system includes a display, processor(s), and a steering assembly configured to cause rotation of the sonar assembly or the motor assembly. The sonar system includes a memory including computer program code that causes the processor(s) to cause the sonar transducer element(s) to emit sonar beam(s), receive sonar return data from a coverage volume of the sonar transducer element(s), generate a sonar image of the coverage volume based on the sonar return data, receive an input from a user, determine a target in the underwater environment based on the input, and cause the steering assembly to adjust the coverage volume to maintain the target within the coverage volume as the watercraft moves relative to the target.

摘要： A sonar system for a watercraft, including a shaft defining a top and a bottom end. The system includes a first attachment operatively connected to the top end of the shaft, and a second attachment operatively connected to the bottom end of the shaft including a transducer assembly. The first attachment defines a first member pivotably connected to the top end of the shaft, and a handle member rotatably attached about the first member. The second attachment defines a second member pivotably connected to the bottom end of the shaft, and a bracket member rotatably attached about the second member. The system comprises a first connector extending between the first and second members and configured to cause reciprocal movement between the first and second members. The system comprises a second connector extending between the first and second members and configured to cause reciprocal rotation between the first and second members.

摘要： Sonar steering systems offering improved functionality and ease of use for an operator (e.g., an angler) are provided. A sonar steering system is configured to automatically adjust the directional coverage volume of the sonar system in a hands-free manner to allow the operator to focus on other tasks. Some such sonar steering systems are configured to adjust the directional coverage volume of the sonar transducers to maintain a target such as an area of interest (AOI) within the sonar display despite movement of the watercraft relative to the target. Accordingly, the coverage volume may be automatically adjusted to maintain the aim of the sonar transducers at a target that is moving through the water, such as a school of fish.

摘要： Sonar systems and related methods are provided. A sonar system for a water craft includes at least one transducer element having at least one emitting face. The at least one transducer element is mountable to the water craft. A sonar signal processor is in electronic communication with the at least one transducer element and is operative to associate signals with the at least one transducer element to cause at least one acoustic beam to be emitted from the at least one emitting face in a first beam direction. A beam reflector is mounted with respect to the at least one transducer element such that at least one beam reflecting surface of the beam reflector is positioned along the first beam direction. The at least one acoustic beam impinges upon the at least one beam reflecting surface and is reflected in a second beam direction different than the first beam direction.

摘要： 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.

摘要： A sonar assembly for a watercraft, including an elongated shaft having a top end and a bottom end, and defining a bore that extends from the top end to the bottom end of the elongated shaft, a transducer assembly secured to the bottom end of the elongated shaft, an elongated member having a top end and a bottom end, the elongated member being disposed within the bore of the elongated shaft, the bottom end of the elongated member being operatively connected to the transducer assembly such that movement of the elongated member with respect to the elongated shaft rotates the transducer assembly within a vertical plane with respect to the watercraft.
