Provided are a sonar system, transducer assembly, and method for imaging an underwater environment. The sonar system may include a housing having a transducer array defining first and second rows of transducer elements positioned at a predetermined distance. The first row of transducer elements may include at least first and second transducer elements configured to convert sound energy into first and second sonar return data. The second row of transducer elements may include at least third and fourth transducer elements configured to convert sound energy into third and fourth sonar return data. A sonar signal processor may be configured to process the first and second sonar return data and third and fourth sonar return data to generate respective first and second array sonar return data corresponding to a plurality of first and second receive beams and generate 3D sonar return data by correlating the angles associated with the receive beams. Transmit Sonar Pulses into a Body of Water 2000 Receive, via a First Transducer Element of a First Row of Transducer Elements in a Transducer Array, First Sonar Returns from the Transmitted Sonar Puises and 2005 Convert the First Sonar Returns into First Sonar Return Data Receive, via a Second Transducer Element of the First Row of Transducer Elements in a Transducer Array, Second Sonar Retuns from the Transritted Sonar Pudses and 2010 Convert the Second Sonar Returns into Second Sonar Return Data Receive, via a Third Transducer Element of a Second Row of Transducer Elements in a Transducer Array, Third Sonar Retums from the Transmitted Sonar Pulses and 2015 Convert the Third Sonar Returns into Third Sonar Return Data Receive, via a Fourth Transducer Element of the Second Row of Transducer Elements in a Transducer Array, Fourth Sonar Returns from the Transmitted Sonar 2020 Pulses and Convert the Fourth Sonar Returns into Fourth Sonar Return Data Process, via a Sonar Signal Processor, the First Sonar Return Data and the Second Sonar Return Data to Generate a Plurality of First Array Sonar Retum Data 225 Corresponding to a Plurality of First Receive Beams Each Oriented at Different Predetermined Angleas Process the Third Sonar Return Data and the Fourth Sonar Return Data to Generate a PIrality of Second Array Sonar Retum Data Corresponding to a Plurality of Second 2030 Receive Beams Each Oriented at the Different Predetermined Angles -- ------ -- -- -- -- -- -- -- --- --- ------ --- --- ---- --- --- - - Generate 3D Sonar Return Data by Generating One or More Second Angles within Each of the Plurality of First Receive Beams by Comparin g the Plurality of First Array Sonar Return Data and the Plurality of Second Array Sonar Return Data at Each of the Different Predetermined Angles Generate a 3D Image based on the Generated Set of 2040 3D Sonar Retun Data |
