We consider the estimation of two-dimensional (azimuth and elevation) direction-of-arrival (DOA) using a pair of uniform circular arrays under a coherently distributed source model. Since the coherently distributed source is characterized by four parameters, the nominal azimuth DOA, angular extension of the azimuth DOA, nominal elevation DOA, and angular extension of the elevation DOA, the computational...
In this paper, we consider the problem of estimating the nominal directions of arrival (DOA) and angular spreads of multiple distributed sources. Distributed sources arise due to the presence of local scattering and impairment in wave propagation. This problem is encountered in wireless communications due to the presence of scatterers in the vicinity of the mobile or when the signals propagate through...
