Minimum variance beamforming using polarization sensitive array
Muhammad Ishtiaq Ahmad, Zhiwen Liu, Yougen Xu · 2008
In this paper we study an accurate interference rejection capability of a minimum-variance polarization sensitive (MVPS) beamformer using a uniform linear array of crossed dipoles. The interference cancellation is done in the spatio-polarized domain since MVPS beamformer search in both the direction of arrival and polarization domains. Also, MVPS beam-former has the capability of handling more signals than the scalar array having the same number of sensors in a single beam. We have also analyzed that there will be no beam when the desired and interference EM signals are same in nature.
