Abstract :
We propose a direction-of-arrival (DOA) estimation technique for ultra-wideband electromagnetic waves, which allows for the effect of antenna mutual coupling. This technique is comprised of ultra-wideband interferometry, multiple signal classification (MUSIC), and databases. The effectiveness of our scheme is demonstrated through numerical examples.
