Abstract: A marine sonar system comprises a sonar transducer, an attitude sensor, and a processing element. The sonar transducer is configured to transmit a sonar beam into a body of water according to a transmit electronic signal, receive reflections of the sonar beam, and output a receive electronic signal according to the reflections of the sonar beam. The attitude sensor is configured to determine an attitude angle of a marine vessel with which the marine sonar system is utilized and to output an attitude electronic signal whose value varies according to the attitude angle. The processing element configured to receive the attitude electronic signal receive and, based on the attitude electronic signal, control the output of the transmit electronic signal to the sonar transducer.
