在本文中，我们提出了一种基于插值的近场阵列校准方法。基于对接收信号模型的分析，通过校正矩阵对位置相关误差进行建模。通过对校正矩阵进行插值，可以获得数值伪校准数据。所提出的方法允许我们通过少量测量来校准密集网格上的阵列响应。仿真结果表明该方法在近场阵列标定中具有良好的性能。
In this paper, we present an interpolation-based method for near-field array calibration. Based on an analysis of the received signal model, the position-dependent errors are modeled by a correction matrix. By interpolating the correction matrix, pseudo calibration data can be obtained numerically. The proposed method allows us to calibrate the array responses on a dense grid by taking a small number of measurements. It is shown via simulations that this method has a good performance in near-filed array calibration.
