摘　　要：本文在仅根据无人机发射的方向信息的情况下,研究无人机纯方位无源定位问题.基于圆的几何性质建立定位模型,确定定位模型中所需发射信号无人机的最小数量,并通过迭代法构建调整模型,得到无人机群位置的调整方案.最后对调整模型的精确度进行评估.In this paper,the problem of azimuth-only passive positioning of the unmanned aerial vehicles(UAVs)is studied only based on the direction information of UAVs.Based on the geometric properties of the circle,a positioning model is established to determine the minimum number of UAVs required to transmit signals in the positioning model,and the adjustment model is constructed by an iterative method to obtain the positioning scheme of UAVs.Finally,the accuracy of the adjustment model is evaluated.
