Antenna beamforming for interference cancellation in radar-wireless spectrum sharing

In this work, an effective beamforming approach is introduced to eliminate wireless interference in both mainlobe and sidelobe directions based on a coherent phase-coding multiple-input multiple-output (MIMO) radar platform. The simulations are carried out for spectrum sharing between air traffic control (ATC) radar at Miami International Airport and Sprint wireless communication systems. The simulation results demonstrate that the ATC radar can effectively eliminate both mainlobe and sidelobe interferences generated by wireless base stations (BS) during spectrum-sharing operations.
