摘要

In order to resolve direction finding problems in the impulse noise,a direction of arrival(DOA)estimation method is proposed.The proposed DOA estimation method can restrain the impulse noise by using infinite norm exponential kernel co-variance matrix and obtain excellent performance via the maxi-mum-likelihood(ML)algorithm.In order to obtain the global opti-mal solutions of this method,a quantum electromagnetic field op-timization(QEFO)algorithm is designed.In view of the QEFO al-gorithm,the proposed method can resolve the difficulties of DOA estimation in the impulse noise.Comparing with some tra-ditional DOA estimation methods,the proposed DOA estimation method shows high superiority and robustness for determining the DOA of independent and coherent sources,which has been verified via the Monte-Carlo experiments of different schemes,especially in the case of snapshot deficiency,low generalized signal to noise ratio(GSNR)and strong impulse noise.Beyond that,the Cramér-Rao bound(CRB)of angle estimation in the im-pulse noise and the proof of the convergence of the QEFO al-gorithm are provided in this paper.
