Abstract
A sonar system for transmitting and/or receiving sonar beams with a desired beam pattern or patterns. The system has a transducer having a linear array of transducer elements, which is driven by element driving signals to project a sonar beam and which generates element receive signals in response to a received sonar signal or sonic wave. A control unit controls the transducer and is configured to generate the element driving signals from a waveform signal based on a set of drive pattern weightings associated with a desired beam pattern to project from the transducer. The control unit is also configured to apply a set of receive pattern weightings to the element receive signals, the receive pattern weightings associated with a desired beam pattern to be detected or sensed received by the sonar system. The drive pattern weightings and receive pattern weightings comprise an amplitude component and polarity component.
