对一种新的用于反射面天线辐射远场的快速积分方法进行了研究，采用物理光学法分析，基于辐射场积分计算，考虑积分网格内的相位影响并用闭合表达式表示，显著减少了积分所需网格数，加快了赋形反射面天线辐射远场的计算速度，并能与其他方法组合以进一步提高辐射远场的计算速度。模拟计算结果与直接积分法比较结果表明方法可靠且有效。

A new fast integral method for reflector antenna far field was studied in this paper. Based on physic optics （PO） and integral and influence of each integral grid＇s phase was a closed express, the number of integral grids required would decrease a lot while the influence of each integral grid＇s phase on radiation field was considered. The rate of computing radiation field was improved very much. The method could combine with other methods for computing radiation field with ease. The computation results showed this method was reliable and valid.
