摘　　要：将馈源辐射场分解为多个高斯波束(GB),其相应的参数由反射面天线形状与馈源类型决定,其展开系数通过最小平方法或点匹配法计算得到。反射后所形成的高斯波束的参数通过参考文献的相关公式计算得到,而反射高斯波束的展开系数通过反射面天线上电流连续性方程组计算得到。模拟计算结果表明与物理光学法(PO)相比较,该方法具有计算速度快、与工作频率无关的优点。The source can be spread into a set of Gaussian beams（GBs）,whose correlative parameters depend on both shape of reflector and the type of source,and the spread coefficients can be computed by the method of least square or point-matching.The correlative parameters of reflected GBs can be computed by some formulas and the spread coefficients can be gained by solving the current continuity equations.GB method has higher computation speed and the same computation accuracy compared with PO method.In addition,the rate computation of GB method has nearly no relationship with work frequency.
