本文提出了一种新的高精度天线近场无相位测量方法。重建过程是从经典的光学全息图的方法移植。全息图的强度分布只记录在一个NF扫描平面上。该方法利用已知参考天线产生的照射波,通过数值乘法重建被测天线的复场。此外,当再现全息图从测量平面背投影到孔径平面时,AUT的所需复场在孔径平面中被区分,并被低通滤波器有效地选通。仿真和实验结果都证明了该方法的可行性和准确性。
This letter presents a novel and highly accurate method for antenna near-field (NF) phase-less measurement. The reconstruction process is transplanted from the classical optical hologram approach. The hologram intensity distribution is recorded only in one NF scanning plane. The illumination wave, regenerated from the known reference antenna, is applied to reconstruct the complex field of antenna under test (AUT) by a numerical multiplication. Moreover, when the reconstructed hologram is back-projected to aperture plane from the measurement plane, the desired complex field of AUT is distinguished in the aperture plane and gated by a low-pass filter efficiently. Both simulations and experiments demonstrate the feasibility and accuracy of the proposed method.
