| Abstract | 在一维分数阶Fourier变换(FRFT,Fractional Fourier Transform)的基础上,给出了二维FRFT的积分表示.通过对口径电流分布辐射场的分析,得到了口径辐射场与口径电流分布二维FRFT的关系.对于两种极限情况的讨论,表明二维FRFT可以一致地适用于Fresnel和Fraunhofer区辐射场的表示. |
| Other Abstract | The integral rep resentation of two dimensional FRFT is p roposed.On the base of the definition of one-dimensional fractional Fourier transform (FRFT ),A fter analyzing the radiated field of an aperture current distribution,the relationship between th is field and the 2D-FRFT of the current distribution is p resented.Discussions on two limitation cases show that the 2D-FRFT can p rovide a uniform ly effective tool for the computation of aperture radiation both in Fresnel and in Fraunhofer regions |
