Claim 0:
1. A sonar array system comprising:
a plurality of sonar arrays, each sonar array configured to receive transmit electronic signals and transmit corresponding sonar beams into a body of water in a forward direction and a downward direction, each sonar array including a plurality of groups of sonar transducer elements, each group including a first sonar transducer element electrically connected to the first sonar transducer elements of the other groups and a second sonar transducer element electrically connected to the second sonar transducer elements of the other groups; and
a sonar signal processor configured to communicate a plurality of transmit electronic signals to the sonar arrays, the transmit electronic signals including:
a first transmit electronic signal to be received by the first sonar transducer element of each group and including a periodic waveform having a first phase, and
a second transmit electronic signal to be received by the second sonar transducer element of each group and including a periodic waveform having a second phase,
wherein a distribution of power between the sonar beams transmitted in the forward direction and the sonar beams transmitted in the downward direction varies according to a difference in the first phase and the second phase.
