Abstract
A sound navigation and ranging (SONAR) transducer system comprises a transmit element and a receive element. The transmit element may be formed from ceramic material and configured to transmit an ultrasonic signal into a body of water. The transmit element may include a first component configured to transmit the ultrasonic signal in a first direction and a second component configured to transmit the ultrasonic signal in a second direction. The receive element may be formed from polyvinylidene difluoride (PVDF) in the shape of a sheet of material and configured to receive a reflection of the ultrasonic signal after the ultrasonic signal is reflected from objects in the body of water. The receive element may include a first section configured to receive reflections from the first direction and a second section configured to receive reflections from the second direction.
