摘要：

Based on backward transformation method (BTM), the probe distance error analysis in z-axis for phased array calibration is described. When BTM is employed in phased array calibration to obtain the electric field over the radiation aperture of antenna, the Taylor expansion of probe distance error is used for analyzing the accuracy of reconstructed aperture field. It is found that probe distance error less than 1/35 of a wavelength is recommended. To verify this conclusion, the measured results demonstrate the validation of this analysis, which is helpful in the near-field calibration for phased array.
