| Abstract: | A novel array calibration method based on the subspace approaches in the presence of amplitude and phase errors on high-resolution direction-of-arrival(DOA)estimation of multiple sources is presented in this paper.This calibration method is easy to implement in practice and achieves good results in estimation.Computer simulations are conducted to show the improvement in robustness and resolution,the high performance in precision,and the good prospect in engineering applications by calibration. |
