Wideband Coherent Signals Direction-of-Arrival Estimation based on Matrix Reconstruction Algorithm
Ming Xin · Fire Control and Command Control · 2010
According to the theory of spatial smoothing, a new algorithm which is based on data matrix reconstruction for Direction-Of-Arrival (DOA) estimation in the presence of wideband coherent signals is presented. Dividing broadband data into a number of narrow-band data, then reconstruct each sub-band data matrix after dealing them with spatial smoothing. Finally, get the average array covariance matrix through the processing of focusing matrix, also estimate the direction of signals by the signal-subspace method. Simulation experiments prove the effectiveness of the method.
