| 摘 要： | 首先提出了一种由喇叭作为馈源的单反射面天线的设计方法，该方法不需求出馈源喇叭的相位中心位置却可确定出馈源最佳位置；通过数值计算发现：馈源相同、反射面口径大小相同的最大增益值时的赋形球形反射面天线比最大增益值时的球形反射面天线有较优良的电性能，可在垂直面进行宽角搜索；最后给出了计算结果及其分析。

| Abstract: | The design method of a new shaped spherical reflector antenna with a norn feed for wide-an?gle scanning was proposed, in which the phase center position need not to be solved to determine the optimal position of the horn feed. The result of numerical calculation was analyzed. It is found that the shaped spherical reflector antenna has better electrically performance than that of the spherical reflector antenna and can scan in wide angle on the vertical plane, at the maximum gain value under the condi?tion of the same feed source and aperture of the reflector. |
