This study presents the performance analysis of two DOA estimation algorithms, ROOT-MUSIC and ROOT-WSF under severe conditions, responsible of signal deterioration. These algorithms have proven to be effective in the comparative study made in previous studies [1] [2], although, it did not include the constraints that a signal can be subjected to. In this context we evaluated the two DOA estimation algorithms, based on four criterias: high frequency, correlated signal, closely spaced sources and noise detection. ROOT-WSF algorithm provides the most accurate results for detecting the angle of arrival under this hard condition.
