The underwater acoustic positioning system that is used to track underwater vehicles and divers can be divided into a long baseline LBL (Long Baseline), a short baseline SBL (Short Baseline), and an ultra-short baseline USBL or SSBL (Ultra-Short Baseline/Super Short Baseline) system according to the array spacing. The length of the long baseline underwater acoustic positioning array is generally 100–6000 m. It is arranged on the seabed according to a certain geometric shape. The adjacent three or four array elements form a matrix, which is used to measure the underwater target sound source to each element. Distance determines the...
