关于抛物面天线口径场特征的进一步探讨

Make a Further Approach to Aperture Field Feature of Parabolic Antenna

本文遵循电磁场的基本理论,根据数理规律,首先论证了反射镜面的剖面所应具备的形式及其基本性质。接着求出口径上的电磁场,进而归纳出抛物面天线口径场的四大共同特征。最后根据焦点的“位迁”,在导出极点与极线式的基础上,阐述了各型镜面天线口径场的独有待色及其成因。

In this articale. both the form and the basic property which should be possessed for the catoptric face section were demonstrated first,by conforming to the elementary thecry of electromagnetic field and in conformity with the mathematical rule. Next the electromagnetic field on aperture was found,and then proceeded to sum up five common features of aperture field of parabolic antenna. Lasty,according to the focus displacement,and on the basis of pole and polar line formula had been derived,expounded the only one unique fedture and the cause of formation for all types of aperture field of specular antenna.
