摘要

本文分析了噪声近场振幅数据对相位恢复算法的影响。在信号上加性高斯白噪声。信噪比在3db和60db之间。结果表明，即使在低信噪比的情况下，使用迭代傅里叶变换也可以获得远场数据。

Phase-less planar near-field antenna measurements: Noise analysis

This paper analyses the effect of noisy near-field amplitude data on the phase retrieval algorithm. Additive white Gaussian noise is applied on the signal. Signal-to-noise ratios between 3 dB and 60 dB are considered. It'll be shown that using the Iterative Fourier Transform the far-field data can be obtained even under low signal-to-noise ratio.
