摘要： A system is provided for imaging an underwater environment. The system includes a transducer assembly with at least one transmit transducer element and an array of receive transducer elements. Each receive transducer element is configured to receive sonar returns and form sonar return data. A sonar signal processor is configured to receive the sonar return data from each receive transducer element and generate sonar image data. The sonar return data from all of the receive transducer elements may be summed and used to form a high-definition 1D (e.g., time-based) sonar image. The sonar return data from only a subgroup may be summed and used to form a lower-definition 1D sonar image. In some systems, an array of series-connected transmit transducer elements can be used. The orientation of the emitting faces of the array may vary slightly to mimic a curved surface for increased beam coverage.

摘要： Various implementations directed to a depth display using sonar data are provided. In one implementation, a marine electronics device may include a sonar signal processor and a memory having a plurality of program instructions which, when executed by the sonar signal processor, cause the processor to receive sonar data from a transducer array disposed on a vessel, where the sonar data corresponds to a marine environment proximate to the vessel. The memory may also have program instructions which, when executed by the sonar signal processor, cause the processor to generate point cloud data based on the received sonar data. The memory may further have program instructions which, when executed by the sonar signal processor, cause the processor to generate a depth display based on the point cloud data, where the depth display includes a depth line representing an underwater floor of the marine environment.
