Abstract :
A least squares estimation algorithm for the azimuth and elevation angles as well as range of a single near-field source impinging on a uniform circular array is proposed. By exploiting the centro-symmetric array configuration, two correlation functions are devised to obtain their closed-form estimates. It is shown that the proposed method gives comparable estimation performance with that of the conventional MUSIC scheme but the former is much computationally simple.
