Abstract :
This paper proposes the forward-backward spatial smoothing with overlapped and augmented arrays (FBSSOA) to improve the conventional spatial smoothing for DOA (Direction-Of-Arrival) estimation. The computer simulation using FBSSOA with MUSIC demonstrates the effectiveness of the FBSSOA in improving the estimation accuracy and the angular resolution of MUSIC.
