Executive Summary

In this paper, the authors 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 beamformer has the capability of handling more signals than the scalar array having the same number of sensors in a single beam. They have also analyzed that there will be no beam when the desired and interference EM signals are same in nature.
