The underwater acoustic positioning system can be divided into long baseline (LBL), short baseline (SBL), and ultra-short baseline (USBL) or super short baseline (SSBL) systems according to the spacing of the elements. Ultra-short baselinepositioning system array length is generally on the order of several centimeters to tens of centimeters, usually less than or equal to half a wavelength, and the phase difference between the received signals of each array element is used to solve the spatial position of the target. All array elements form a sound array, which can be mounted at the bottom of the carrier or suspended from the side of the carrier or installed where fluid noise and structural noise are relatively weak. The ultra-short baseline...
