Abstract
Sonar systems and associated methods are provided herein for sonar image generation. The sonar system is configured to enable rotation of a transducer array that includes at least two transducer elements. The transducer array may be mounted to a trolling motor capable of being rotated. The transducer elements can be positioned to enable use of interferometry to obtain angle information regarding sonar returns. The angle and range of each sonar return can be used to form images, such as a 2D forward looking image of the underwater environment. A heading detector can be used to obtain a heading of the transducer elements to enable creation of a 2D radar-like image of the underwater environment. Additionally, the heading, angle, and range of the sonar returns can be used to form a 3D image of the underwater environment.
