【摘要】 本文介绍了基于无人机系统(UAVS)的E面辐射方向图的新颖测试方法,这在国内尚属首次。使用搭载有实时频谱分析仪和其他辅助设备的无人机来测量米波天线的E面方向图,整个测量可以实时的在实验室里进行分析处理。在解决了重量控制,能源供给等问题之后,通过改变无人机飞行的高度可以得到米波天线在不同角度的辐射值,再通过处理算法最终得到米波天线的部分E面方向图。经试验和仿真验证,测量结果基本正确。后续可以继续通过给无人机增加图传系统、延长飞行时间以得到天线的全E面辐射特性。使无人机飞行轨迹近似圆化或者考虑衰减因子后改进实验数据处理算法,增强频谱分析仪的测量能力等方法来优化整个测量系统的精度。更多还原

【Abstract】 This paper presents a novel method about E-plane radiation pattern measurement based on unmanned aerial vehicle system(UAVS),which is implemented in china for the first time.we use unmanned aerial vehicle loaded with Realtime Spectrum Analyzer and other assistant equipmemts to measure the meterwave antenna’s E-plane radiation pattern.the whole aerial measurement is real-time and can be monitored and analyzed in the laboratory.after solving the weight control and other problems,by changing the height of unmanned aerial vehicle,we get the E-plane radiation pattern at different degree.The result is basically effective and can be improved by adding image transmission system on the unmanned aerial vehicle,sweeping the whole operating frequency band of the antenna,making the track of unmanned aerial vehicle a circle(keep the R unchanged) and enhancing the receive antenna gain of the Spectrum Analyzer.更多还原
