Research on the Method of Improving Positioning Accuracy of Ultra Short Baseline System
The positioning accuracy of the ultra short baseline positioning system is affected by many factors.As one of the many fac-tors,the design of the array has a particularly serious impact on the positioning accuracy of the ultra short baseline positioning system.In view of the role of array in ultra short baseline positioning,this paper develops an improved method of data fusion based on array design,which fuses the preliminary positioning results of each basic array configuration and takes the fusion results as the final positio-ning results.The improved method proposed in this paper is applied to the positioning of the ultra short baseline system,and the test results are verified by the average value and standard deviation of the error.The test results show that the positioning accuracy of the improved USBL system is higher than that of the USBL(ultra short baselines)system of other arrays,which reflects the superiority of this method.
