Marine multibeam sonar device

A marine multibeam sonar device comprising:

• a receiver configured to receive reflections of a sonar beam, the receiver including—
• a plurality of receive channels, each receive channel including a receive transducer configured to generate a receive transducer electronic signal with a polarity, wherein the polarity of a first portion of the receive transducer electronic signals is inverted compared with the polarity of the rest of the receive transducer electronic signals, and
• electronic circuitry configured to receive the receive transducer electronic signals and generate a receive signal including data from each of the receive transducer electronic signals;
• a memory element;
• a processing element in communication with the receiver and the memory element, the processing element being configured to—
• receive the receive signal,
• re-invert the polarity of the data from the first portion of the receive transducer electronic signals,
• generate sonar data from the receive transducer electronic signals,
• generate a plurality of transmit transducer electronic signals, and
• invert a polarity of a first portion of the transmit transducer electronic signals;
• and
• a transmitter in communication with the processing element, the transmitter including—
• a plurality of transmit electronic circuits, each configured to receive and process one of the transmit transducer electronic signals, wherein a first portion of the transmit electronic circuits is configured to re-invert the polarity of the first portion of the transmit transducer electronic signals, and
• a plurality of transmit transducers configured to receive the processed transmit transducer electronic signals from the transmit electronic circuits and to generate the sonar beam.
