摘　　要：天线方向图测量是天线测量的重要内容。针对天线方向图室外测量困难的问题,提出了一种基于生成对抗网络的天线三维方向图室外测量方案。该方案利用无人机对天线方向图数据进行采集,对采集的数据进行修正,获得待测天线和接收天线极化匹配时的直射径数据,最后利用训练好的生成对抗网络重构出天线的三维方向图。仿真结果表明,本方案可以高效、高精度地完成天线三维方向图的测量,具有一定的实用价值。Antenna pattern measurement is an important part of antenna measurement.Addressing the difficulty of outdoor measurement of antenna pattern,this paper presents an outdoor measurement scheme for antenna three-dimensional pattern based on the generative adversarial network.An unmanned aerial vehicle(UAV)is used to collect the antenna pattern data,modify the collected data,and obtain the direct path data when the receiving antennas match with the polarization of the antenna to be measured.Finally,the three-dimensional pattern of the antenna is reconstructed by using the trained generative adversarial network.Simulation results show that the proposed scheme can complete the measurement of antenna three-dimensional pattern efficiently and accurately,showing practical value.
