This paper focused on assessing the effectiveness of the signal Doppler frequency (SDF) method to locate a mobile emitter using a swarm of unmanned aerial vehicles (UAVs). Based on simulation results, we showed the impact of various factors such as the number of UAVs, the movement parameters of the emitter and the sensors on location effectiveness. The study results also showed the dependence of the accuracy and continuity of the emitter coordinate estimation on the type of propagation environment, which was determined by line-of-sight (LOS) or non-LOS (NLOS) conditions. The applied research methodology allowed the selection of parameters of the analyzed location system that would minimize the error and maximize the monitoring time of the emitter position.
本文主要研究了利用无人机群(UAVs)采用信号多普勒频率(SDF)方法定位移动辐射源的有效性。基于仿真结果,分析了无人机数量、辐射源和传感器运动参数等各种因素对定位有效性的影响。研究结果还表明,辐射源坐标估计的准确性和连续性取决于传播环境的类型,该类型由视距(LOS)或非视距(NLOS)条件决定。应用的研究方法允许选择分析定位系统的参数,以最小化误差并最大化辐射源位置的监测时间。
