1. A reflective sonar imaging system, the reflective sonar imaging system comprising:
a reflective sonar imaging assembly including:
a reflective surface defining a concave shape;
a receiving aperture; and
a receiver positioned between the reflective surface and the receiving aperture;
a display; and
processing circuitry,
wherein the reflective surface is configured to cause sonar returns to be reflected as reflected sonar returns toward the receiver, wherein the sonar returns enter the reflective sonar imaging assembly through the receiving aperture, wherein the receiver is configured to receive the reflected sonar returns, wherein the receiver is configured to generate sonar return data using the reflected sonar returns that are received, wherein the processing circuitry is configured to receive the sonar return data and generate one or more sonar images based on the sonar return data, wherein the display is configured to present the one or more sonar images.
