摘　　要：目的:以战场士兵搜索为背景,研究一种新的基于无人机移动信标的战场士兵定位方法。方法:无人机沿"∞"模型飞行,机载信标获取相对地理位置信息,并且周期性地发送唤醒信号;士兵节点被唤醒后,发送RSSI数据包,再次进入休眠状态;移动信标接收士兵节点RSSI数据包,在接收位置形成该节点对应的虚拟信标:计算士兵节点到所对应的虚拟信标的距离矩阵,从而进一步计算士兵节点的相对地理坐标。结果:仿真测试随机布设20个结构相同的士兵节点,当平均每个士兵节点对应的虚拟信标数为8.3个时,平均定位误差为7.78%。结论:基于无人机移动信标的定位方法具有较高的定位精度。Objective To develop a new method of localization based on mobile beacon for searching and rescuing of the wounded in battlefield.Methods When the unmanned aerial vehicle（UAV） was flying along the model ＂∞＂ the beacon in the vehicle got the relative location information,and sent the periodic wake -up signals.When receiving the wake -up signals,the unknown position soldiers sent RSSI,and fell asleep again.Beacon collected the RSSI and formed a corresponding virtual beacon.Beacon calculated the distance between the unknown node and the corresponding virtual beacons,and calculated node relative location,which would be sent to the rear headquarters.Results In simulation,20 soldier nodes with same style were laid randomly.When the average virtual beacon per 1 soldier was 8.3,the average localization error was 7.78%.Conclusion The proposed localization method based on mobile beacon in UAV possesses a better location accuracy,which is expected for battlefield soldier location.｜
