DOA estimation of ultra-wideband EM waves with MUSIC and interferometry

Abstract—In this paper, we propose a direction-of-arrival (DOA) estimation technique for ultra-wideband electromagnetic waves, which allows for the effect of the antenna mutual coupling. This technique is comprised of a ultra-wideband interferometry, multiple signal classification (MUSIC), and databases. The effectiveness of our scheme is demonstrated through numerical examples. Index Terms—Direction-of-arrival (DOA) estimation, interfer-ometry, multiple signal classification (MUSIC), mutual coupling of antennas, ultra-wideband (UWB) electromagnetic waves. I
