Abstract :
An algorithm to estimate angles of arrival (azimuth and elevation) and polarization associated with narrow-band plane waves is presented. Electromagnetic energy is assumed to be collected by an L-shaped array of small crossed dipoles. The estimation of the directions of arrival is based on the matrix pencil method, whereas polarization is obtained via a least squares problem
