摘　　要：采用基尔霍夫公式,并利用计算机编程技术实现了对圆口径天线的远场(电场)的精确计算,同时得到天线的方向图,分析了其辐射特性,并将程序的计算结果与相关文献中的理论值作对比,验证了该方法的准确性及有效性。The far-field （electric field） of circular aperture antenna was accurately calculated with Kirchhoff＇s formula and programming technique. The antenna pattern was portrayed while its radiation Characteristics were analyzed. Besides, the accuracy and validity of this method was validated by comparing the calculated result with theoretical result in the relative literature.
