In this paper, we first obtain the FRFT of the uniform impulse-train sampled signals, and based on it, we deduce sampling theorem and reconstruction formula for bandpass and lowpass signals with FRFT.
本文首先得到了均匀冲激串采样信号的FRFT，然后在此基础上导出了FRF T域上带通信号和低通信号的采样定理和重构公式。
Extending the uniform intersensor spacing beyond a half-wavelength would lead to a set of cyclically ambiguous direction-of-arrival estimates, in accordance with the spatial Nyquist sampling theorem.
按照耐奎斯特空间采样定理，阵元间距超过半波长将会带来方位估计的周期性模糊。
