Electronic steering of multiple nulls for circular arrays
Abstract
This letter shows that an n-element circular array can have up to n-1 independent zeros in the 360 deg range of its directional pattern and describes suitable phasing networks to steer independently these zeros. Experimental results are presented for steering two nulls with a 4-element circular array, and the significance of certain pattern-distortion terms is briefly discussed.
