Abstract :
In this paper we discuss spatial superresolution methods applied to the received data of a conformal array antenna. The "sequential MUSIC" and the "sequential alternating projection" methods are derived. Besides the angles of arrival we estimate additionally the polarization states of the received signals. The theoretical derivations are verified and experimental results are shown.
