Abstract

As underwater detection demands continue to grow across fields such as marine scientific research, resource exploration, and underwater engineering, the performance and application scope of sonar systems have become a focal point of research. Against the backdrop of rapid technological advancement and an increasing emphasis on marine development, enhancing the precision, efficiency, and adaptability of sonar systems has emerged as an urgent challenge to be addressed. This article summarizes the current research status of various types of sonar systems, and it also elaborates on the operation principle of the sonar system in terms of the classification of single-beam and multi-beam. This article then further analyzes the advantages and disadvantages of different sonar systems and concludes the applicable scenarios for them. In terms of principle, this article explains the differences and advantages/disadvantages between single-beam and multi-beam technologies. For instance, single-beam has a low cost but is not very precise and has limited applicable scenarios; multi-beam is more advanced and can accurately survey complex seabed topographies, but it has a higher cost. This paper generalizes the existing underwater sonar systems, which can help identify the deficiencies of the current sonar systems and facilitate further research and development.
