Claim 22:
23. A multiplexed phased array multibeam sonar system, comprising:
a control head having a user display;
a transducer unit coupled via a high speed data link to the control head, the transducer unit including a transmit (TX) element configured to generate a sonar ping to ensonify an ensonification cone of water in which the transducer unit is deployed, a receive (RX) array configured to receive sonar echoes resulting from the sonar ping contacting targets in the ensonification cone, a digital signal processor (DSP) configured to process the sonar echoes from a single one transmit-receive cycle into sonar display information, and a multiplexer (MUX) coupled between the RX array and the DSP and configured to selectively couple at least a first portion of the RX array to the DSP during a first time of the single one transmit-receive cycle and a second portion of the RX array during a second time of the single one transmit-receive cycle;
wherein the transducer unit communicates the sonar display information generated by the DSP from the single one transmit-receive cycle via the high speed data link to the control head; and
wherein the control head plots the sonar display information generated by the DSP from the single one transmit-receive cycle received from the transducer unit on the user display;
wherein the TX element is a curved ultrasonic transducer; and
wherein the TX element includes a curved reflector affixed thereto configured to provide directionality of ultrasonic energy of the sonar ping.
