Design and Research of Underwater Searching and Positioning System for Amphibious Equipment

The amphibious equipment is used in the marine environment, due to the improper operation, unexpected equipment failures, battle damage and other reasons may cause equipment sinking. In order to search quickly and locate accurately the sinking equipment, the underwater searching and positioning system for amphibious equipment is designed in this paper based on the ultra short baseline positioning method. It proved that the system performance, environmental adaptability and positioning accuracy and so on meet the actual requirements through the tests. These not only provided effective technical support for searching and locating the sinking equipment, but also had the significant economy and military benefits.
