摘要
高效率馈源，口径分布所产生的辐射可以用复源点场有效地表示，文中导出了对给定馈源确定其等效义源点在参数的公式，并以口径场菲涅尔变换及角谱等方法为参考，通过数值计算比较了它们在口径面上、辐射近区及远区场分布的差别。
Field emitted from Comlex Source Point(CSP)is effectively used here to simulate the radlation from a higj efficiency feed horn with an aporture field mode.Formulascalculating the parameters of the equlvalent CSP to a given horn are derived out by two meth-ods. Numerical calculation of the aperture,near and far-field distributions are carried out andthe comparison between the results from the two methods here and that from the classicalmethod are presented.
