Abstract :
This paper deals with the near-field DOA-Matrix method for source localization using an array antenna. To apply this method for the estimation of the coherent sources, the spatial smoothing is incorporated into this method. The computer simulation along with SAGE algorithm demonstrates that the proposed method provides higher estimation accuracy of coherent source locations.
