Abstract—Root MUSIC is one of the most important algorithms that address the DoA issue for its discrete estimations for non-coherent sources. However, coherent signals cannot be discriminated by using the algorithm, even they are adjacent in this paper. We will concentrate on utilizing root MUSIC advantages discrete estimation for DoA by using as simple modification for covariance matrix in root MUSIC algorithm to capable to handle signals of coherent sources as well as factors related to number of snapshots and number of element array. As well will result in enhancing ROOT MUSIC algorithm resolution for adjacent coherent sources to 1 degree space which will be called ECRMUSIC (Enhanced Coherent-Root MUSIC).
Index Terms—Coherent sources, direction of arrival, resolution enhancement, root MUSIC.
