摘要

提出了一种低复杂度的近场到远场变换(NF2FFT)方法。该方法分别采用惠更原理和舍尔库诺夫原理，不同之处在于是否采用等效电流和积分限制。以喇叭天线为例，实现了NF2FFT。计算结果表明，该方法是近场天线测量的备选方案。

Theoretical Method and Analysis of Spherical Near-field to Far-field Transformation Based on Equivalence Principle

In this paper, a low-complexity near-field to far-field transformation (NF2FFT) method is proposed. The method employs Huygen’s and Schelkunoff principles respectively, and the difference lies in whether to adopt the equivalent electric current and the integral limitations. As an example, NF2FFT is implemented on a horn antenna. The calculation results show that the proposed method is a candidate solution to near-field antenna measurement.
