一种新型的太阳能无人机分布式相控阵天线

Novel distributed phase array antenna of solar powered UAV

由于远距离传输、小口径安装、精确波束指向等诸多因素,传统的相控阵天线无法满足临近空间长航时太阳能无人机的通信需求。针对此问题,提出了一种新型的太阳能无人机分布式相控阵天线,以实现高数据率远距离传输;基于分布式阵列方法解决天线安装问题;采用基于应变测量元件的波束校正方法实现精确波束指向。设计了一种Ka频率的分布式相控阵天线,通过仿真,验证了本文提出方法的正确性。

Due to some limitations （long-distance transmission, small-caliber mounting, accurate beam steering）, thecommunication demand of long endurance solar powered unmanned aerial vehicle （UAV） cannot be satisfied by using thetraditional phase array antenna. According to these questions, a novel distributed phase array antenna for UAV wasproposed. It employed phase array antennas to realize the high data rate and long-distance transmission; and then, itimplemented the method based on distributed subarray to solve the installation problem; finally, it also employed the beamcorrection method used strain measuring devices to establish accurate beam steering. As a sample, a Ka-band distributedphase array antenna was designed. The feasibility of the proposed method is validated by the simulation.
