Base on the mathematical conformation between antenna array distribution to its far field and DFT to IDFT, we discuss how to obtain the array distribution by sampling far field pattern in some space angles based on DFT.

• 利用天线阵列分布及其相应的阵列方向图与离散傅里叶变换对之间在数学上的同构,对不同空间角度上阵列方向图的采样值进行离散傅里叶变换(DFT)来重新确定天线阵列的激励分布。
