本文讨论了在线列阵频率域宽带多波束形成中采用混基 FFT 实现空间Fourier 变换的问题。为了便于比较,本文除了给出混基 FFT 计算结果外,还给出了用增补零值样本点的基2FFT 的计算结果。
In this paper, we discuss the problem of using Fourier transform to realize the Fourier transform in wideband multi-beamforming in online array frequency domain. In order to facilitate the comparison, this paper gives the calculation results of the basis 2FFT with the addition of zero sample points in addition to the results of the hybrid FFT.
