Abstract :
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.
