To meet the needs of marine surveying, resource exploration, and underwater safety, a sonar system capable of both ‘wide-area surveys’ and ‘detailed scans is essential. For this purpose, a wideband multibeam sonar system has been built. This paper analyses and designs the system from the perspectives of wideband transducer design, multi-channel low-noise synchronous data acquisition and processing, amplitude-phase consistency calibration, and multi-beam automatic control. Test results in water bodies such as riverbeds and bridge piers demonstrate the system’s satisfactory application performance.

摘要

To meet the needs of marine surveying, resource exploration, and underwater safety, a sonar system capable of both ‘wide-area surveys’ and ‘detailed scans is essential. For this purpose, a wideband multibeam sonar system has been built. This paper analyses and designs the system from the perspectives of wideband transducer design, multi-channel low-noise synchronous data acquisition and processing, amplitude-phase consistency calibration, and multi-beam automatic control. Test results in water bodies such as riverbeds and bridge piers demonstrate the system’s satisfactory application performance.
