摘要/Abstract

摘要： 提出了一种研究口径辐射的新算法,它将已知的实口径面上的场分布解析开拓,求得一复口径面上的场分布,进而利用相应复口面的Kirchhoff褶积公式,间接但严格地表示出了原口面的辐射特性。就一线性相移口径作了数值计算,并与相应的标准解作了比较。

关键词: 口径辐射, 复射线, Kirchhoff公式

Abstract: Kirchhoff's complex spatial convolution formula is developed as a new algorithm for radiation from a aperture. It is based on hte idea of analytic ectention that the original aperture field is extended to a complex plane.and then the kirchhoff's complex spatial-convolution formula makes up an indirect and rigorous representation of radiation from a plane aperture.Numerical tests confirm its correctness and efficiency.

Key words: aperture radiation, complex ray, lirchhoff's formula
