摘　　要：借鉴国外无人机浮标多基地探测阵型,首先选定两种适用于多基地航空声纳浮标的探测阵型;其次从声纳方程出发推导了多基地探测范围,并结合具体探测阵型给出探测面积的分析结果;然后根据多基地探测的测距测向信息,采用最小二乘算法对选定探测阵型中有效探测范围内的定位误差结果进行分析;最后对选定的探测阵型进行探测面积和定位误差的对比仿真。仿真结果表明:在固定的探测范围下,按照“田字格”探测阵型可以得到最大的探测面积和最优的定位误差,但消耗的浮标数量最多;而按照“十字”探测阵型,采用不同的基线长度,系统可在浮标使用数量、探测面积和定位误差之间进行平衡,该仿真结果可为工程应用提供一定的参考价值。Based on foreign UAV buoy multi-base detection formations,two detection formations for multi-base aero-sonar buoys are selected at first. Secondly,the multi-base detection range is derived from the sonar equation,and the analysis results of the detection area are given in combination with the specific detection formations. Then,based on the range and direction information of multi-base detection,the least-squares algorithm is used to analyze the positioning error within the effective detection range of the selected detection formations. Finally,detection area and positioning error of the two selected detection formations are compared by simulations. The simulation results show that under the fixed detection range,the maximum detection area and the optimal positioning error can be obtained with the "Matt" detection formation,but the number of buoys consumed is the largest. While according to the "Cross" detection formation,using different baseline lengths,the system can trade off among the number of buoys used,the detection area and the positioning error. As a result,this simulation can provide some reference to engineering applications.
