摘　　要：分析了一种多元阵超短基线阵水声定位几何算法,对多元阵声学定位算法与传统正交四元阵算法做分析对比,并与常见阵型的定位精度作比较。仿真结果表明,在阵元条件等一致的情况下,五元均匀圆阵精度最高,复杂度也最大,四元三维正交阵、四元平面正交阵,精度依次降低,复杂度也依次降低。对超短基线定位系统优化阵型、提高超短基线定位精度有借鉴意义。This paper analyzes a geometric algorithm for underwater acoustic location of multi-sensor 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 positioning 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 accuracy and the largest complexity.The accuracy of the four-element three-dimensional orthogonal array and the four-element plane orthogonal array is reduced orderly,and the complexity is also reduced orderly.It has reference significance for optimizing the formation and improving the positioning accuracy of USBL positioning system.
