Abstract :
We present a new adaptive beamforming method for coherent interference cancellation, which is based on the Duvall-structure to remove the desired signal component from the received signal. The proposed beamformer can suppress as many as M/2 coherent interferences for even M, where M is the number of array sensors, though the Duval beamformer can suppress a single coherent interference only. Simulation results show that it converges to the steady-state very quickly.
