    Abstract: Provided are a sonar system and transducer assembly for producing a 3D image of an underwater environment. The sonar system may include a housing mountable to a watercraft having a transmit transducer that may transmit sonar pulses into the water. The system may include at least one sidescan transducer array in the housing that receives first and second sonar returns with first and second transducer elements and converts the first and second returns into first and second sonar return data. A sonar signal processor may then generate a 3D mesh data using the first and second sonar return data and at least a predetermined distance between the transducer elements. An associated method of using the sonar system is also provided.

    Abstract: Provided are a sonar system and transducer assembly for producing a 3D image of an underwater environment. The sonar system may include a housing having a transmit transducer that may transmit sonar pulses into the water. The system may include at least one transducer array in the housing that receives first, second, and third sonar returns with first, second, and third transducer elements and converts the first, second, and third returns into first, second, and third sonar return data. A sonar signal processor may then generate a first and second set of 2D sonar data based on the sonar return data, generate a third set of 2D sonar data based on a correlation of the first and second set of 2D sonar data, and generate a 3D mesh data based on the third set of 2D sonar data. An associated method of using the sonar system is also provided.

The method may include processing, by a sonar signal processor, first sonar return data and second sonar return data from first and second transducer elements of at least one transducer array to generate live 3D mesh data. The method may include determining a position associated with the live 3D mesh data that corresponds to the position of the watercraft when the first sonar return data and the second sonar return data was received, and may include updating a stored 3D mesh data with at least a portion of the live 3D mesh data based on the position.
