Description

(1) Technical field [0001] The invention relates to the field of underwater acoustic measurement, in particular to an underwater acoustic measurement device for underwater target tracking, positioning and navigation. (2) Background technology [0002] At present, the acoustic orientation system (Acoustic orientation System) is still the mainstream of underwater target navigation and positioning, and underwater acoustic positioning technology has always been an important research topic. The main means of underwater target positioning and tracking is the underwater acoustic positioning method which relies on geometric principles. Among these methods, according to the baseline length of the acoustic positioning system, we divide the acoustic positioning system into three types: long base line positioning system (Long Base Line), short base line positioning system (Short Base Line) and ultra-short base line positioning system (Ultra Short Base Line). Among them, compared with ...
