The errors of antenna array element position and orientation affect phase and gain of received array signal, respectively. Direction of arrival (DOA) algorithm based on eigenvalue decomposition is very sensitive to gain/phrase errors of array signal. Thus, it is necessary to correct the gain/phrase errors of array signal. Considering uniform linear antenna array model, this paper proposes a “blind” calibration algorithm. It estimates array’s gains and phases errors using the subspace method, no needing known reference signals. DOA of the incident signal and error parameters are estimated separately using iterative approach. The simulation results show that its convergent rate is fast and its convergent precision is high.
