Abstract
Mitigation of the effects of multipath signals is provided. Such mitigation can include electronically steering the main beam of a receive pattern associated with a phased array antenna away from a transmitting antenna. In addition, a phase taper is applied to groups of antenna elements to create a null in the main beam, bifurcating that beam. The multipath signal may be placed in or towards the null, while the direct path signal may be placed on one of the halves of the main beam adjacent the null, such that the signal strength of the multipath signal is attenuated as compared to the signal strength of the direct path signal.
