Abstract
A beamformer for adaptively nulling out jammers which arrive from uncertain directions is presented. The noise density term was considered in the beamformer. Theoretically, it can produce exact nulls in jammer directions with no constraint on the power of receiver noise. The results of simulations show that it can reject jammers more effectively than other beamformers
