Since the existing underwater GPS positioning technology can only position underwater targets equipped with acoustic transponders, this study proposed a method of positioning underwater combining targets based on an ultra short baseline forward-looking sonar acoustic device. The mathematical model of the obtaining longitude and latitude coordinates of the underwater target in the WGS84 ellipsoidal coordinate system was established. A group of data was given based on the measuring state, and Monte Carlo simulation was carried out to study the effects of the random errors in the indirect measurements in the algorithm on the positioning accuracy and the combined effect of the random errors in the indirect measurements in the algorithm on the positioning accuracy at different geological locations. The preset target was measured in the offshore waters of Dalian, confirming the validity of the proposed algorithm.
