摘　　要：在天线测量领域,为了评估天线在实际工作环境中的性能,现场天线测量技术受到越来越多的关注,借助无人机对天线性能指标进行现场测试评估的技术在近年来取得了显著进展。当前无人机天线测量系统可以分为两种:一种是在满足远场条件下直接测量天线方向图、增益等指标,一种是在近场测量后进行数据变换获得远场天线指标。本文总结了基于无人机的天线测量系统研究现状,提出一种外场无人机测量方案,通过S波段标准增益喇叭天线辐射方向图外场测试实验,验证了系统的可行性,进一步对测量误差进行了分析。In the field of antenna measurement,in order to evaluate the performance of the antenna in the actual working environment,more and more attention has been paid to on-site antenna measurement technology.The technology of on-site testing and evaluation of antenna performance indicators with the help of Unmanned Aerial Vehicle(UAV)has made significant progress in recent years.The current UAV-based antenna measurement systems can be divided into two types,one is to directly measure the antenna pattern,gain and other indicators under far-field conditions,and the other is to obtain far-field antenna indicators by data transformation after near-field measurement.This paper summarizes the research status of UAV-based antenna measurement systems,and proposes an outfield UAV measurement scheme.The feasibility of the system is verified by the outfield test experiment of the radiation pattern of the S-band standard gain horn antenna,and the measurement error is further analyzed.
