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: A system for reforming sonar emissions from a sonar transducer element or an array of sonar transducer elements is provided. 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).

Abstract: A system for controlling sonar beam shapes is provided. The system comprises at least one sonar transducer element having an emitting face. The at least one sonar transducer element is configured to generate a sonar beam having a path. The system also comprises a horn that is configured to rest within the path of the sonar beam. The horn is configured to reform a beam shape of the sonar beam.
