Application Analysis of an Ultra-short Baseline Array Positioning Algorithm
This paper analyzes a geometric algorithm for underwater acoustic location of multi-sen-sor ultra-short baseline(USBL)array.The multi-element array acoustic positioning algorithm is analyzed and compared with the traditional orthogonal four-element array algorithm,and the posi-tioning accuracy is compared with that of common arrays.The simulation results show that in the case of consistent element conditions,the five-element uniform circular array has the highest accu-racy and the largest complexity.The accuracy of the four-element three-dimensional orthogonal ar-ray and the four-element plane orthogonal array is reduced orderly,and the complexity is also re-duced orderly.It has reference significance for optimizing the formation and improving the positio-ning accuracy of USBL positioning system..
