摘　　要：首先利用等光程条件导出了抛物环面上的点与副面上的点的关系公式;其次,巧妙地利用微波光学强度定律、几何光学法和物理光学法给出了计算“附加相位校正副面的多波束抛物环面天线”的辐射方向图公式;最后,利用所得的辐射方向图公式对一个实际天线进行了理论计算,理论计算值和实验测试值吻合异常良好。Firstly, the important relation formula for the points of parabolic torus reflector and subreflector is obtained by using the equivalent ray path condition. Secondly, the formula of radiation pattern for multiple-beam parabolic torus reflector antenna with phase-correcting subreflector is given by using the law of microwave optics intension, geometrical optics method and physical optics method skillfully; Finally, an antenna has been calculated with the radiation pattern formulas in this paper, and the result of calculation is considerably consistent with the result of experiment.
