A marine multibeam sonar device comprises a processing element and a transmitter. The processing element generates a plurality of transmit transducer electronic signals and inverts a polarity of a first portion of the transmit transducer electronic signals. The transmitter is in communication with the processing element and includes a plurality of transmit electronic circuits and a plurality of transmit transducers. Each transmit electronic circuit receives and processes one of the transmit transducer electronic signals, wherein a first portion of the circuits re-inverts the polarity of the first portion of the transmit transducer electronic signals. The transmit transducers receive the processed transmit transducer electronic signals from the transmit electronic circuits and generate a sonar beam.

Marine multibeam sonar device

A marine multibeam sonar device comprises a transmitter, a memory element, and a processing element. The transmitter includes a plurality of transmit channel circuits, each connected to one of a plurality of transmit transducers. Each transmit channel circuit is configured to receive a transmit transducer electronic signal. The transmit transducers are oriented in a linear array that is configured to form a transmit acoustic beam. The processing element is in communication with the transmitter and the memory element and is configured to generate the transmit transducer electronic signals, each including a serial binary bitstream.

A sonar transducer array assembly comprises a first flexible circuit, a second flexible circuit, and a plurality of transducer elements. The first and second flexible circuits each include a first side, a second side, and a plurality of adhesive areas spaced apart and positioned in a line along one edge of the first side. The transducer elements each include a first surface attached to one of the adhesive areas of the first flexible circuit, an opposing second surface attached to one of the adhesive areas of the second flexible circuit, and a third surface positioned between the first and second surfaces. The transducer elements form a linear array with the third surface of each transducer element in alignment and configured to transmit and receive an acoustic pressure wave.
