Abstract

A sonar transducer assembly is provided including a transducer configured to transmit one or more sonar beams into an underwater environment, a housing that holds the transducer, at least one electrical cable that enables electrical signals to be transmitted between the transducer and a computing device, and a conductive enclosure disposed around at least a portion of the transducer and electrically connected to a ground line of the electrical cable to create a shielded volume. The conductive enclosure reduces an electromagnetic field within the shielded volume.
