摘　　要：研究圆形阵天线近场/远场的单元辐射场叠加法.该算法利用单元辐射场叠加思想,在不引入任何近似条件下对圆形阵天线远区场和近区场进行计算,减少了计算时间.通过具体算例与已有文献的比较,证明了该方法的正确性.该方法具有操作简便的特点,可在实际的天线分析中得到广泛应用.A convenient method of circular array near/far field calculation is studied. The calculation for both the near field and the far field of a circular array is carried through by getting the sum of the radiation field due to each element, without the introduction of any approximation. This can save much of the computing time. The validity of this method is proved by comparing the results calculated and the published data. It can be widely applied in antenna analysis as it can be implemented easily.
