摘要

提出了一种基于NSI等近场测量系统的相控阵标定新方法。通过对单单元天线近场和阵列近场的测量，对测量数据进行两次傅里叶变换和一次傅里叶反变换，提取校准参数。该方法在很短的时间内实现了幅值和相位的标定。最后以一维阵列的标定实例验证了该方法的有效性。

Calibration method of phased array based on near-field measurement system

A new phased array calibration method based on near-field measurement system such as NSI is proposed in this paper. By measuring a single element antenna near-field and array near-field, calibration parameter is extracted from measured data with twice Fourier Transformation and once Inverse Fourier Transformation. Both amplitude and phase calibration is realized by this method in a very short time. A calibration example of a one-dimensional array is used to validate the proposed method.
