چکیده انگلیسی
The SBL system (Short Baseline System) is usually utilized by offshore working vessels when performing its underwater orientation task so as to facilitate the exploitation of abundant benthal resources, therefore, the precise distance between the vessel and underwater targets for SBL system's estimation module are highly emphasized. However, hydrological data cited in the SBL system's estimation module is not real-time information and is difficult to accurately measure, which causes the calculation errors. Studies with regard to symmetrical SBL system are carried out by most of the researchers these days, yet research in this text shows the advantage to the asymmetrical SBL system's sensor on the vessel's bottom to be installed at discretion to measure and calculate the position. In addition to the locus equation used in the traditional position calculation, Haussiam Elimination, Cramer's rule, 3D geometry relation theory as well as substitution corrections applied to this asymmetrical SBL system to educe the correction for relative geometrical position between the underwater beacon and the sensor on the ship bottom. Through numeric simulation analysis, this SBL system is proved to be a high precision acoustic positioning system based on its quick correction and high precision position calculated by the asymmetrical SBL system established in this study.
