    Abstract: A system is provided for imaging an underwater environment. The system includes one or more arrays of transducer elements. Each array is operated at a fixed phase shift and varies in frequency so as to beamform multiple sonar return beams of a first range of angles and a second range of angles. The arrays can be oriented to cover the gap in sonar coverage for other arrays to create a continuous arc of sonar coverage. Accordingly, a 2D live sonar image can be formed. One or more of the multiple sonar return beams facing downwardly can be selected and used to form downward sonar images that anglers are used to, without requiring separate transducer elements. Fish arches formed using multiple sonar return beams can be positioned appropriately within a high resolution downward sonar image to form a desirable combined sonar image.

    Abstract: Example devices and systems are provided herein for mounting a transducer within a hull of a watercraft. Such devices and systems include a housing with a base and at least one wall defining an interior volume, along with a mount assembly within the interior volume. The mount assembly includes a buoy, a transducer, and a pivot axle or a gimbal. The mount assembly is freely pivotable about a pivot axis of the pivot axle or about a pivot point of the gimbal such that an orientation of the mount assembly is subject to a force of gravity. The housing and the mount assembly is configured such that an emitting face of the transducer points in a direction that is parallel to the force of gravity when the housing is tilted, such as toward a floor of the water.

    Abstract: A reflective sonar imaging system is provided. The system includes a reflective sonar imaging assembly. The reflective sonar imaging assembly includes a receiving aperture, a reflective surface defining a concave shape, and a receiver positioned between the reflective surface and the receiving aperture. The system also includes a display and processing circuitry. The reflective surface is configured to cause sonar returns to be reflected as reflected sonar returns toward the receiver. The sonar returns enter the reflective sonar imaging assembly through the receiving aperture, and the receiver is configured to receive the reflected sonar returns. The receiver is configured to generate sonar return data using the reflected sonar returns that are received, and the processing circuitry is configured to receive the sonar return data and generate one or more sonar images based on the sonar return data. The display is configured to present the sonar image(s).

    Abstract: Sonar systems and related methods are provided. A sonar system for generating one or more sonar images includes first and second transducer elements each having at least one emitting face. The sonar system also includes a sonar signal processor in electronic communication with the first and second transducer elements to cause transmission of signals from the first and second transducer elements to cause at least one first acoustic beam to be emitted from the first emitting face in a first beam direction and at least one second acoustic beam to be emitted from the second emitting face in a second beam direction. The first and second transducer elements are positioned such that a gap is formed therebetween. The gap is configured to facilitate movement of a fluid therein so as to contribute to an emission of sound power in both the first beam direction and the second beam direction.

The system comprises the sonar transducer element or the array of sonar transducer elements. The sonar transducer element or the array of sonar transducer elements define an emitting face and are configured to transmit sonar signals along path(s). The system also comprises a horn comprising surface(s). Surface(s) are positioned adjacent to or in a spaced apart manner from the emitting face of the sonar transducer element or the array of sonar transducer elements so that the surface(s) are positioned at least partially in path(s) such that at least some of the sonar signals transmitted from the sonar transducer element or the array of sonar transducer elements are redirected based on interaction of the at least some of the sonar signals and surface(s).
