摘　　要：为了保证相控阵雷达的性能,它的天线现场校准越来越受到重视。本文首先介绍相控阵雷达天线现场校准的现状,提出目前存在的问题。然后分析光学电磁场探测技术优势,阐述基于光子技术的相控阵雷达天线现场校准实现的可行性,建立了现场校准装置。通过实验验证,该技术能实现对相控阵雷达天线现场校准,具有高精度,对天线的辐射场的影响较小,能满足相控阵雷达天线现场校准要求。The on-site calibration of antennas is getting much more attention now because it can greatly impact the performance of the phased array radar. This paper introduces the current situation of on-site calibration of antennas and puts forward some existent problems. It focuses on analysing the advantages of optical-electromagnetic field detect technique and proving on-site calibration of phased array radar antennas based on optical technology is entirely feasible, by building the on-site calibration device and doing some experiments. With this technology, parameters of phased array radar antennas can be calibrated accurately with less impact on radiation field of antennas. It can meet the requirements of the on-site calibration of phased array radar antennas.
