Abstract
A transducer system comprises a first frequency steered transducer array element and a second frequency steered transducer array element that is spaced apart from the first frequency steered transducer array element. The system additionally includes a processing element in communication with the first and second frequency steered transducer array elements. The processing element is configured to receive a first receive electronic signal from the first frequency steered sonar array element, receive a second receive electronic signal from the second frequency steered array sonar element, compare a difference in amplitude between the first receive electronic signal and the second receive electronic signal to determine a cross-track position of an underwater target, and control a display to present an indication of the cross-track position of the underwater target.
