Abstract：Aiming at the multiplicative array errors calibration problem,a novel maximum likelihood (ML) array errors estimator by using the spatial-domain information and time-domain waveform information of the calibration sources is presented in this paper.The proposed calibration method is implemented via concentrated Newton iteration and alternative iteration with fast convergence ratio and high numerical robustness.Furthermore,the Cram閞-Rao bound (CRB) of the array errors parameters is derived in the two cases:one where the time-domain waveform information of the calibration source is unknown;and the other where the time-domain waveform information of the calibration source is known up to a complex factor.The simulation experiments validate the superiority of the novel algorithms.
