A novel direction of arrival estimation technique using a single UWB antenna

In this paper, we propose a novel DOA estimation technique for broadband signals using a single UWB antenna inspired by the human auditory system. The received spectra of the UWB antenna are incident angle dependent in the x-y, x-z and y-z planes. The estimated DOA is then obtained by evaluating the correlation coefficients of the measured spectra with pre-determined incident angle dependent spectra. The proposed DOA technique demonstrates the feasibility of finding the DOA using a single UWB antenna, although with reduced accuracy comparing with the case of two antennas with a scatter.
