The source number and direction of arrival (DOA) estimation are two key issues in array signal processing, and the estimation performance will degrade severely for closely spaced sources with large power differences. Especially for the weak sources, the interference from the closely spaced strong sources will disable most traditional algorithms to estimate accurately. In this paper, a novel joint...
The direction of arrival (DOA) estimation is a key issue in array signal processing, and there are many well-known methods, e.g., Capon, MUSIC, Root-MUSIC and some other DOA estimation algorithms in the literature. Nevertheless, the effective DOA estimation for closely spaced multiple sources with large power differences is still a difficult problem due to the deteriorated resolution for the low power...
