We propose an improved direction-of-arrival estimation technique for ultra-wideband (UWB) electromagnetic waves, which allows for the effect of the antenna mutual coupling. This technique is comprised of a UWB interferometry, a Root-MUSIC, and a database. The effectiveness of our scheme is demonstrated through a numerical example.
