无人机遂行飞行中的纯方位无源定位
Uavs Carry Out Azimuth-Only Passive Localization in Flight

本文针对无人机编队飞行时的无源定位问题，基于纯方位无源定位方法和极坐标函数推导，对无人机遂行编队飞行时位置信息进行理论分析，建立几何模型，讨论求得部分无人机的位置信息。通过建立极坐标系，给出编队飞行过程中位置调整方案，同时针对圆周上的无人机编队三点定位，利用信号源与信号接收源之间的位置偏差建立几何模型进行定位，该方法充分考虑到了外界对无人机集群飞行时的电磁干扰问题，具有较高的准确性和普适性。
In this paper, based on azimuthing-only passive positioning method and derivation of polar coordi-nate function, the position information of UAV in formation flight is analyzed theoretically, the geo-metric model is established, and the position information of some UAV is discussed and obtained. By establishing polar coordinate system, the position adjustment scheme during formation flight is given. At the same time, aiming at three-point positioning of UAV formation on the circumference, a geometric model is established by using the position deviation between signal source and signal receiving source. This method fully takes into account the external electromagnetic interference of UAV cluster flight, and has high accuracy and universality.
