Development status and trends of underwater search technology for wrecked targets

Abstract

In view of the increasingly rising number of marine accidents recently, this paper presents the development status and trends of underwater search technology. The current underwater crash targets are classified, the research status of underwater search and rescue strategies is analyzed, and three kinds of data and model search methods are discussed using the underwater search technology as the object. The development of underwater search platforms and equipment is prioritized. Considering the shortage of current search technology, this paper finally provides an outlook for underwater search technology from four perspectives: enhancing wrecked target positioning, improving search capabilities and intelligence of underwater robots, strengthening the clustering ability, and multi-platform cooperative networking and improving the performance and data processing abilities of acoustics acquisition installation.
