Abstract: A transducer assembly comprises a housing, a frequency steered transducer array element positioned within the housing, a conical transducer element positioned within the housing, and a scanning transducer element positioned within the housing. The frequency steered transducer array element includes a plurality of piezoelectric elements and is configured to receive a transmit electronic signal including a plurality of frequency components and to transmit an array of sonar beams into a body of water, each sonar beam transmitted in an angular direction that varies according to one of the frequency components of the transmit electronic signal. The conical transducer element is configured to transmit a conically-shaped sonar beam into the body of water. The scanning transducer element is configured to transmit a fan-shaped sonar beam into the body of water.
