KIRCHHOFF's FALTUNG FORMULA OF COMPLEX APERTURE AND COMPLEX RAY SIMULATION OF APERTURE RADIATION
-
摘要: 本文基于解析延拓的概念,由實口徑的Kirchhoff褶積公式導出了復口徑的Kirchhoff褶積公式。理論分析和數(shù)值計算表明,利用復口徑Kirchhoff褶積公式可以實現(xiàn)對孔徑輻射場的復射線束仿真,從而為進一步研究孔徑輻射場在復雜媒質(zhì)中的傳播提供了一種新方法。

Abstract: The Kirchhoff s faltung formula of complex aperture is proposed as a new method for radiation from a plane aperture. It is based on the idea of analytic extension that the original aperture field is extended to a complex plane, and then the Kirchhoff s faltung formula makes up an indirect and rigorous representation of the radiation from a plane aperture. Numerical calculations comfirm its effectiveness and correctness. -
