Performance improvement of localization of radio sources by using spatial smoothing processing in near-field DOA-Matrix method with SAGE algorithm

This paper deals with the near-field DOA-Matrix method with SAGE algorithm, which is applied for source localization using a uniform linear array antenna. In this paper, we investigate the effect of spatial smoothing processing (SSP) on the performance of the near-field DOA-Matrix method with SAGE algorithm. The computer simulation using electromagnetic field analysis shows the SSP improves the source localization performance with the help of SAGE algorithm especially when the sources are correlated with each other.
