提出了一种基于元表面（MS）反射面的波达方向（DoA）估计方法，并从理论上证明了该方法的性能。该系统能够通过半波长偶极子天线的单个接收天线来估计DoA。通过优化MS单元的布置，与未优化的MS反射面天线相比，DoA的估计精度得到提高。此外，该系统具有与使用3单元线性阵列天线的DoA估计系统几乎相同的估计精度。
Direction of arrival (DoA) estimation using a meta-surface (MS) reflector with an optimized arrangement of MS elements is proposed and its performance is theoretically proved. The system is capable of estimating DoA by a single receiving antenna which is a half-wavelength dipole antenna. By optimizing the arrangement of MS elements, the estimation accuracy of DoA is improved compared to a non-optimized MS reflector antenna. In addition, the system has almost the same estimation accuracy as the DoA estimation system using a 3-element linear array antenna.
