Abstract—This article first discusses the simulation of ML, MUSIC, ROOT-MIUSIC and spatially Smoothed base MUSIC and then compares the algorithms based on their estimation of the accuracy level angels from two different sources, having demonstrated the result of simulation of the four algorithms in comparison tables, it is observed that ROOT-MUSIC algorithm have high level of accuracy in estimation and recognition of close angles. MUSIC algorithm and Spatially Smoothed version of MUSIC algorithm come next.

Index Terms—DOA, ML, MUSIC, Root MUSIC, Spatially Smoothed algorithms.
