Abstract In this paper, a new method is proposed to estimate the DOA of wideband coherent signals. The orthogonality of projected subspaces method is used to estimate DOA. This method does not require the primary information of DOA for focusing matrix and need not the sector dividing of interpolated method. And it can deal with coherent signals and array calibration by using the Toeplitz method to modify the data covariance matrix. The simulation results illustrated the effectiveness of this method.
