口徑天線在任意口徑分布時的沖激響應
IMPULSE RESPONSES OF APERTURE ANTENNAS WITH ARBITRARY APERTURE DISTRIBUTIONS
-
摘要: 本文從夫累涅爾-基爾霍夫標量衍射場方程出發(fā),證明了任意形狀的并饋口徑天線在任意口徑幅度分布時的沖激響應和端饋矩形口徑天線在任意口徑幅度分布時的沖激響應都可以用口徑幅度分布表達出來;而矩形口徑天線在口徑分布可分離時的沖激響應和圓形口徑天線在口徑分布圓對稱時的沖激響應則為上述一般情況的特例。

Abstract: On the basis of the equation of Fresnel-Kirchhoff scalar diffraction field, it is shown that the impulse responses of parallel-fed aperture antennas of arbitrary configurations with arbitrary aperture amplitude distributions and those of end-fed rectangular aperture antennas with arbitrary aperture amplitude distributions can all be expressed in the aperture amplitude distributions, and that the impulse responses of rectangular aperture antennas with separable aperture distributions and those of circular aperture antennas with circularly symmetric distributions are special cases of the above general ones. -
