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 Nyquistsamplingtheorem.
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。
2
The rate of sampling, related to the Nyquisttheorem.
抽样的频率,这与奈奎斯原理有关。
3
The samplingtheorem shows that aliasing can be avoided if the Nyquist frequency is greater than the bandwidth, or maximum component frequency, of the signal being sampled.
