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).
