Abstract
In the work presented here we consider the problem of direction of arrival (DOA) estimation and gain-phase errors calibration. We propose a new method which is based on the eigendecomposition of the Hadamard product of the covariance matrix and its conjugate. This method requires neither the presence of calibration sources nor previous calibration information as initialization. Moreover, it performs independent of the phase errors. Simulation results demonstrate the effectiveness of the proposed method.
