摘要
无人机载空间电磁场测量系统综合了无人机、电场测量探头、软件控制技术,可进行广播电视、基站及雷达等大型发射天线的空间电磁场测量。空间电磁场测量系统采用三轴全向电场探头设计、抑制无人机电机干扰等技术,能适应强电磁干扰工作环境。该系统具有自由空间布点监测、按照程序控制的自动监测及实时数据回传地面等功能。系统在某短波天线、移动通信基站天线的空间电磁场测量应用中,测量得到的电磁场分布与理论值具有很好的一致性。
The space electromagnetic field measurement system of UAV integrates UAV,electric field measurement probe and software control technology,which can measure the space electromagnetic field of large transmitting antennas such as radio,television,base station and radar.The space electromagnetic field measurement system adopts three-axis omni-directional electric field probe design,suppression of UAV motor interference and other technologies,which can adapt to the strong electromagnetic interference working environment.The system has the functions of free space monitoring,automatic monitoring according to program control and real-time data back to the ground.In the application of space electromagnetic field measurement of a short wave antenna and a mobile communication base station antenna,the measured electromagnetic field distribution is in good agreement with the theoretical value.
