Zhou Weia · Video Engineering · 2013
According to the data received by the array antenna,a direction-of-arrival(DOA) estimation algorithm for wideband coherent sources is presented based on Toeplitz matrix reconstruction.Firstly,the covariance matrix which includes the information of DOA is obtained from the data received by Toeplitz matrix.Secondly,the covariance matrix is processed with the focusing matrix to get the new covariance matrix in the same frequency.Finally,the DOA estimation can be obtained by the high resolution subspace approach.Simulation results prove the effectiveness of this method.
