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...
In this paper, we present a new high resolution algorithm to localize multiple sources in near-field. After focusing on a pre-estimated location, the covariance matrix of the received signal is found to have the same structure as in the far-field situation, which allows the estimation of bearing with far-field subspace methods. With the estimated bearing, the range estimation of each source is consequently...
