【摘要】 本文讨论场相关定理用于计算反射面天线效率的两种不同公式。已经严格证明了差异主要来自接收场和发射场的感应电流作了不同的物理光学近似。文中给出了两者的适用条件。更多还原

【Abstract】 This paper describes two different formulae of the field correlation theorem for the calculation of the efficiency of reflector antennas. It has deen proved strictly that the difference is due to making the different approximations of physical optics for the induced currents of the transmitted field and received field. The condi- tions in which these formulae can be applied are given.更多还原
