Multiplexed phased array sonar system for consumer fishfinders
A recently granted patent (Publication Number: US11914066B1) discloses a multiplexed phased array multibeam sonar system designed to enhance underwater imaging capabilities. The system comprises a control head with a user display, a transducer unit connected to the control head via a high-speed data link, and a digital signal processor (DSP) for processing sonar echoes into display information. The transducer unit includes a transmit element for generating sonar pings and a receive array for capturing echoes from targets in the water. A multiplexer selectively couples portions of the receive array to the DSP during each transmit-receive cycle, allowing for efficient processing and display of sonar information on the user interface.
The patent details the technical specifications of the system, including the use of a curved ultrasonic transducer, specific carrier frequencies for sonar pings, and advanced signal processing techniques such as base banding and down sampling. The system's ability to resolve multiple beams and suppress noise through beamforming filtering is highlighted, showcasing its potential for high-resolution underwater imaging. Additionally, the method outlined in the patent for generating sonar images on the user display emphasizes the precise control and optimization of the sonar data processing workflow. Overall, the patent reveals a sophisticated sonar system that combines hardware and software components to deliver detailed and accurate underwater imaging capabilities for various applications.
