本文对500米口径球面射电望远镜L波段19单元多波束馈源的性能进行了验证。在电波暗室中测量了阵列近场辐射方向图，并与HFSS在相同条件下的模拟辐射方向图进行了比较。测量和模拟之间观察到非常好的协议。
The performance of an L-band 19-element multibeam feed for the five-hundred-metre aperture spherical radio telescope is verified here. Radiation patterns have been measured in an anechoic chamber in the radiating near field of the array and compared with simulated radiation patterns from HFSS for the same conditions. Very good agreement is observed between the measurements and simulations.
