Range and DOA Estimation of Near Field Source via the Fourth-order Statistics
By exploiting the fourth-order statistics,two novel algorithms are proposed for DOA and range estimation of the near-field narrow-band sources.Compared with most proposed methods which can identify only p sources with a(2p+1)-ele-ment ULA(uniformly linear array),the proposed methods can identify 2p or 2p-1 sources.Moreover,the computational burden of the methods much fewer than conventional one because they do not need any operation of parameters pairing.Simula-tion results show that the two ESPRIT-based methods can provide improved performance over several existing methods because of more efficient use of the information of received signals.
