本文介绍了使用俄克拉荷马大学先进雷达研究中心 (ARRC) 开发的无人机系统 (UAS) 的雷达系统当前现场天线表征和校准的最新情况。定制的大型多旋翼平台具有长续航（约 30 分钟）、高定位精度（< 3cm）和高稳定性，并集成了高精度三轴云台，可容纳天线阵列和脉冲发生器-发射器。该平台设计用于支持 2 GHz 至 10 GHz 的测量，但是，本文中描述的当前设置包括 3×3 元件的 S 波段阵列探头。 RF 探头波束宽度经过优化，可最大程度地减少 UAS 框架的反射，并在飞行条件下提供准确的天线测量。
This paper presents an update of the current in-situ antenna characterization and calibration of a radar system using an Unmanned Aircraft System (UAS) developed by the Advanced Radar Research Center (ARRC) at The University of Oklahoma. A large multirotor platform was customized for long endurance (~ 30 minutes), high positioning accuracy (< 3cm), and high stability, and was integrated with a high precision 3-axis gimbal that holds an antenna array and pulse generator-transmitter. The platform was designed to support measurements from 2 GHz to 10 GHz, however, the current setup described in this article includes an S-band array probe of 3×3 elements. The RF probe beamwidth was optimized to minimize reflections from the UAS frame and to provide accurate antenna measurements in flight conditions.
